Of the 78 different players who have won the Heisman Trophy, there are more players who never played one NFL game (14) and more players who went undrafted (15) than players who went on to be inducted into the Pro Football Hall of Fame (9).

That mixed bag of results among Heisman winners in the NFL means there are plenty of players who simply did not pan out as a pro. Here is a look at the biggest disappointments among recent Heisman winners in the NFL.

This is a ranking of the last 25 Heisman Trophy winners (going back to 1990), not based just on what they accomplished in the NFL, but also taking into account the college football achievements of each award winner.

The Cleveland Browns' decision to move on from Johnny Manziel after just two seasons highlights just how the NFL performances of Heisman winners varies tremendously. While Manziel's NFL career is in jeopardy, the two players who followed him as Heisman winners -- Jameis Winston and Marcus Mariota -- seem to have promising NFL careers ahead of them.

It also should be noted that in this exercise we are not excluding Reggie Bush, who won the Heisman Trophy in 2005 but voluntarily forfeited his trophy in 2010. While records can be vacated years after the fact, you can't take away the memories.

College football teams have been enthusiastic about showing their patriotism on the field.

In honor of Veterans Day, we rank the best of the patriotic uniforms worn by college football teams.

Robert Griffin III and Trent Richardson were the No. 2 and 3 overall picks in the 2012 NFL Draft. The teams that drafted each player thought so highly of their potential that they traded up in order to secure their services.

On Monday, hours after RGIII was relegated to backup duty by the Redskins, the Raiders released Trent Richardson. Richardson was already on his third team after starting his career with the Browns.

Both players are cautionary tales of the perils of trading away valuable draft picks -- possibly mortgaging a franchise's future in the process -- to acquire a player. Here's a look at 15 of the worst NFL trades involving draft picks.

A new college football season means new looks for a number of college football teams. Some come strong, others not so much. Here, we are going to highlight the very best -- with one exception -- of what's to come in 2015.

College football annually presents a wide variety of marvelous player names. Whether the names are totally unique, difficult to pronounce or just plain fun to say, this is a starting lineup of the best names in college football for 2015.

The players on the 2015 college football all-name team don't just possess interesting names, but are also expected to be contributors for their respective teams this fall. Only those who are expected to play made the cut; in other words, if you tune in to watch a game involving that player's team, you should hear said player's name during the broadcast.

Notre Dame (with two enshrinees) and USC (with one) will add to impressive lists of contributions to the Pro Football Hall of Fame when the 2015 class is inducted Saturday. Counting players, coaches and contributors that come from schools (and in some instances, said enshrinee attended multiple schools), Notre Dame and USC pace other colleges in presenting the best lineup of Pro Football Hall of Famers.

However, what are the chances another college could catch them? Well, we also take a look at possible future Pro Football Hall of Fame enshrinees from the schools mentioned below, gauging each program's chances to add to already extraordinary Hall of Fame tallies.

While football fans eagerly await the progress of Winston's NFL career, we'll take a look at what he has to live up to -- on both ends of the spectrum -- with this ranking of the previous 20 quarterbacks to be selected No. 1 overall in the NFL draft.

We have been celebrating college football with our "15 for '15" series, but today we have come to shame it with a look at the 15 most embarrassing games of the season.

Forget picking from among flotsam and jetsam such as Ohio State-Hawaii, FSU-Texas State, Oklahoma-Akron, Oregon-Georgia State and Florida-New Mexico State; those games actually are intriguing compared to the ones we're spotlighting. What we don't like is FBS teams scheduling games against bad FCS teams.

We know that some of the FBS teams we're picking on do have some good non-conference games. And we're aware that some of these spotlighted games were scheduled at the last minute. But that in no way absolves anyone of blame.

All, however, have the goods to make 2015 a memorable season.
