Tim Tebow timeline
Finally? NFL coaches continue to be fascinated by Tim Tebow. The latest is Chip Kelly who is expected to sign the 27-year-old former Heisman Trophy winner this week. NFL Media looks back at Tebow's excellent NFL adventure.

Tim Tebow left the University of Florida as one of the most decorated college football players ever with two national titles and a Heisman Trophy, but draftniks picked apart his unorthodox throwing style and shoddy footwork. A poor performance at the Senior Bowl certainly didn't help matters.

Despite being widely projected as a second-day pick, Tebow was selected 25th overall in the 2010 NFL Draft by the Denver Broncos. Coach Josh McDaniels became enamored with Tebow in the pre-draft process, and Denver traded Baltimore its second-, third- and fourth-round picks to move up and draft the Gator legend.

Rookie hazing got the best of Tebow, as the Broncos' elder statesmen trimmed his hair into a gut-busting friar design.

Tebow scored his first NFL touchdown on the very last play of his first preseason game. He finished 8-for-13 for 105 yards and added a seven-yard touchdown run as time expired.

Through the first 13 games of his rookie season, Tebow was limited to spot duty in the "Wild Horse," a package of plays designed to maximize his bruising running style. The rookie scored his first regular-season touchdown on a 5-yard run against the Jets in Week 6.

A Week 13 loss dropped Denver to 3-9 and officially eliminated them from postseason play. One day later, the Broncos fired Josh McDaniels, the chief influence behind Tebow's draft selection.

With Kyle Orton nursing bruised ribs and the Broncos toiling away at 3-10, Tim Tebow was inserted into the starting lineup against the Raiders. Although Denver lost the game 39-23, Tebow enjoyed an effective debut, going 8-for-16 for 138 yards and a touchdown, and also running the ball eight times for 78 yards, including an inspired 40-yard scoring scamper.

With Tebow in the starting lineup again the following week, Denver fell behind 17-0 at halftime to the visiting Texans. But Tebow rallied the troops after the break, guiding the Broncos to scoring drives on each of their four second-half drives, and Denver prevailed 24-23. Tebow thrilled the Broncos faithful with 308 yards passing.

Tebow entered his sophomore season thinking he would be the Broncos' quarterback, but he took a back seat to Kyle Orton, who thoroughly outplayed him throughout training camp. For a while, it was unclear whether Tebow or Brady Quinn was the Broncos' true backup.

As Denver stumbled out to a 1-4 start, rally cries for Tebow got louder by the week. Broncos fans could be heard chanting "We want Tebow" at multiple games. Eventually a Denver company took to a digital billboard, begging John Fox to play Tebow.

During Denver's bye week, Fox switches quarterbacks from Orton to Tebow, but claims the fans did not influence his thought process. "It's not so much fan outcry as we're in a result-oriented business, and we're 1-4," Fox said. "It's not one guy. We'll see if this helps."

Despite a welcoming road environment in Miami -- thanks to an odd Dolphins promotion that honored the 2008 Florida Gators' national championship -- Tebow played horribly through the first 57 minutes of the game and the Broncos fell behind 15-0, well on their way to 1-5. But in the final 2:44, Tebow miraculously throws a pair of touchdown passes and notches a two-point conversion with his legs to send the game into overtime. Eventually, Denver wins on a 52-yard Matt Prater field goal.

The Lions absolutely mauled the Broncos, 45-10. Detroit sacked Tebow seven times and converted his two turnovers into touchdowns.

On the heels of planking, Tebowing becomes a nationwide trend, practiced by some high-profile celebrities and athletes. What is Tebowing? Well, according to the man himself: "To get down on a knee and start praying, even if everyone else around you is doing something completely different."

The Broncos stormed the Black Hole in Week 9 and took it to the Raiders, 38-24. Much of Denver's success came from the implementation of the read-option, an offensive tactic normally reserved for the college ranks. The Broncos churned out 299 yards on the ground, including 163 from Willis McGahee and 118 from Tebow.

Tebow completed just two passes (in eight attempts) against the Chiefs in Week 10, but one of them was a 56-yard, fourth-quarter touchdown to Eric Decker. The Broncos prevailed, 17-10.

Facing a 13-10 deficit to the Jets in Week 11 with less than six minutes remaining, the Denver offense took over on its own 5-yard line, having punted on its previous eight possessions. Tebow proceeded to calmly march the Broncos 95 yards to paydirt, accounting for 92 yards on his own, including the game-winning, 20-yard scamper with 58 seconds left.

With Chargers kicker Nick Novak lining up for a game-winning field goal in overtime, Tim Tebow began praying on the Broncos sideline. Was he asking The Almighty for a miss? "I might have said that. Or maybe a block. Maybe all of it," Tebow admitted postgame. His prayers were answered, as Novak couldn't convert the 53-yarder. Tebow proceeded to drive Denver for the game-clinching field goal. In the 16-13 win, Tebow ran the ball 22 times -- the most carries by an NFL quarterback since 1950.

The Broncos outlasted the Vikings, 35-32 in Week 13, with Tebow enjoying the most efficient passing game of his professional career. He completed 10 of his 15 passes for 202 yards and two touchdowns, giving him a near-perfect quarterback rating of 149.3. Tebow helped set up a pair of field goals in the game's final 93 seconds, including Matt Prater's 23-yarder as time expired.

The Broncos won their sixth straight game in highly improbable fashion, leading many to sight divine intervention. "If you believe," Tebow said, "then unbelievable things can sometimes be possible." Unbelievable, indeed. The Bears took a 10-0 lead deep into the fourth quarter, but Tebow rallied the Broncos in the last few minutes of regulation, with Matt Prater nailing a 59-yarder to send the game into overtime. An OT fumble by Marion Barber, who also had an inexplicable (and costly) mental error late in the fourth quarter, set up Prater's 51-yard game-winner.

Tebow and the Broncos struggled mightily down the stretch, losing their final three games of the season to New England, Buffalo and Kansas City. But Denver's 8-8 record was good enough to take the AFC West. Tebowmania was playoff-bound.

Nobody gave the Broncos much of a chance in their wild-card matchup against Pittsburgh, with the Steelers boasting the top-ranked defense in football. But a 20-point explosion in the second quarter -- the period that had haunted Denver all season -- gave the Broncos a shocking 14-point lead at the half. Pittsburgh stormed back after the break and sent the game into overtime. On the very first play of the extra period, Tebow hit Demaryius Thomas in stride across the middle of the field, and the second-year wideout did the rest of the work. Thomas stiff-armed Ike Taylor and raced 80 yards to the end zone for a walk-off touchdown that sent Denver fans into a frenzy. Tebow passed for 316 yards and two touchdowns, while running for 50 yards and an additional score.

Tebowmania took a bite out of the Big Apple following his trade to the New York Jets. But the taste went sour fast. Tebow was little used and posted just 102 rushing yards and completed just six passes. His tenure will be remembered for his infamous jog in the rain, Mark Sanchez's pass hitting him in the head and when he broke two ribs against the Seattle Seahawks. The Tebow Show opened with great fanfare, but ended up a Broadway bust. He was released on April 29, 2013.

Tebow didn't have to go far to get his next shot. New England Patriots coach Bill Belichick signed Tebow on June 10, 2013. But this proved to be a short summer vacation, as Tebow only played in a few preseason games where he went 11-for-30 for 145 yards, threw two touchdowns and two interceptions. He was cut on August 31, 2013.

In December of 2013, Tebow joined ESPN as a college football analyst. He would mainly appear on the SEC Network, but also co-hosted Good Morning America before Super Bowl XLVIII.

Philadelphia Eagles coach Chip Kelly is expected to signed Tebow this week. He will compete against a crowded quarterback field, including Sam Bradford, who he beat for a national championship in 2009.
