The fastest ball carriers on their way to the end zone during Week 4 all hit at least 20 mph: Minnesota Vikings running back Adrian Peterson (21.89 mph), Carolina Panthers cornerback Josh Norman (21.19), Denver Broncos running back Ronnie Hillman (21.07), Philadelphia Eagles wide receiver Riley Cooper (20.82) and New Orleans Saints running back C.J. Spiller (20.80).

Michael Vick wiped away any concerns about his advanced age, recording the game's top three speeds by a ball carrier, all above 20.0 mph. Two of them (21.15 and 20.07) were in the top 10 in the entire league this week.

Le'Veon Bell traveled 66.67 yards switching fields for an 11-yard touchdown run. Vick turned back the clock to throw the final block that got Bell into the end zone, traveling 46.33 yards. Bell got up to 19.45 mph on the play following Vick's block. Bell has been quickly slotted back into the workhorse role -- he finished with the most distance covered as a ball carrier this week (614 yards).

After being an active sit last week, Chris Ivory returned to his workhorse status. Only Le'Veon Bell covered more distance as a ball carrier, but Ivory did it while recording only two top speeds over 16 mph.

In becoming the first running back to score three touchdowns in back-to- back games since LaDainian Tomlinson, Devonta Freeman took advantage of some big holes provided by his offensive line and hard running to shed tacklers. Freeman ran through holes of 3.16, 2.37 and 4.15 yards, respectively, on his three touchdown runs. He also broke tackles on each play, moving at least 5 mph faster than the defender at the point of contact.

Josh Norman extended Jameis Winston's difficult transition to the NFL with two interceptions, taking one back for a touchdown. On the return, Norman reached a top speed of 21.19 mph, the second-fastest speed on a touchdown this week.

Travis Benjamin went a second straight game without a game-breaking play, but he continues to be a North-South receiver. Against the Chargers, he covered an average of 2.07 yards of distance per yard gained as a receiver and is at 1.74 on the season. For comparison, Jarvis Landry, the prototypical "possession receiver," covered 2.67 yards per yard gained through the first four weeks.

The Todd Gurley experiment didn't take long to get going for St. Louis, as he recorded the third-fastest speed by a running back with the ball in Week 4. Gurley exploded for a 52-yard run in the fourth quarter, hitting 20.84 mph, putting to bed fears of his ACL tear from last year. He also hit 19.33 mph on a 30-yard gain that allowed the Rams to take a kneel-down and end the game.

Green Bay proved it can win without the offense putting up big points. Its defense harassed Colin Kaepernick to the tune of six sacks and an interception. On those six sacks, Packer defenders got to Kaepernick in an average of 4.8 seconds.

Russell Wilson spent most of Monday night on the run from Lions defenders. Combining scramble runs and pass plays, Wilson covered 678.11 yards. For context, that's more than all but 14 running backs covered from scrimmage over an entire game, with our without the ball.
