vicent allen is my pick
he didnt play in the nfl due to a very serious knee injury that he incurred while playing at isu. and he wasn't the right size for the league at that time (5-8, 185 pounds), but he was without a doubt the best player that i ever saw at isu.
how good was he? think darrin sproules of the san diego chargers. or maurice jones-drew of the jacksonville jaguars. that was vincent allen at his very best. small, quick, elusive, strong legged, quick cuts, breakaway speed, could pass block with the best, smart runner.
just try this on for size: combine sproules' elusiveness, speed and quickness to the outside with jones-drew's burst and power up the middle and you have vincent allen.
unforuntately, when he played in college, smaller sized running backs weren't considered big enough to play in the nfl. he ended up playing for a few years up in the cfl, but his knee injury finally took a toll.
he rushed for 1,000 yards every year that he was a sycamore. he missed his junior year as he recovered from knee surgery and returned for a fifth year and still gained over 1,000 yards.
i have talked to people at the college football hall of fame in south bend about trying to get him nominated for inclusion. he was that good.
here is my top five:
1. vincent allen
2. jim brumfield (played in the nfl with the new orleans saints and pitsburgh steelers. was drafted by the saints).
3. tunch ilkin (pro bowl offensive tackle with the pittsburgh steelers)
4. vencie glenn (played in the senior bowl and the blue-gray game; long nfl career with the new england patriots, san diego chargers, minnesota vikings, new orleans saints, new york giants; drafted by the patriots, traded to san diego where he spent most of his nfl career; set nfl record for the longest interceptions in a game to be returned for a touchdown against denver broncos and qb john elway).
5. Wayne Davis (drafted by the san diego chargers).
