1. Dri Archer - Running Back -Kent State
Speed isn't the only attribute a running back needs to be successful in the NFL, but when a player has a lot of it, he can be an instant difference maker.
Dri Archer ran an official 4.26 seconds in the 40-yard-dash. Not only was that the best time this year, and the only sub-4.3 time this year, but it was also the second fastest ever run at the combine.
The all time record belongs to Chris Johnson of the Tennessee Titans; a three-time pro bowler who has run for over 1,000 yards in each of his first six season including 2,006 yards back in 2009.
Archer's biggest drawback is that he's very small by NFL standards at just 5'8" 173lbs.
Don't expect him to be the workhorse that Johnson turned out to be, but do expect him to turn in some highlight reel plays from the moment he gets on an NFL field, starting with kickoff and punt returns.
Also, with the success of fellow small-guy Tavon Austin for the St. Louis Rams (5'9" 174lbs) last season, expect teams to be willing to take a big play threat, like Archer, in the early rounds.
