Well I am one of the belief that while we will get a running back, I don't think we need to spend a high pick. He would replace Rainey's spot as a return specialist for an immediate impact.
Williams relies on his speed, but that being said, Williams is very fast and I like how quickly and smoothly he transitions in space. He also looks to me like one of the best receiving running backs in this draft. He almost always gains positive yards and has sub 4.4 speed. Usually backs with speed have a bunch of negative plays to go with their home-runs, but Williams isn't one of those guys. He is a shorter back but definitely not small. He's 5'8 but 198 lbs. Rainey was 5'9 180lbs and while Williams is not as fast, was more productive in college than Rainey. And finally as to the level competition, yes I agree slightly... but Utah State was ranked at the end of the year at #22 and this was out of the WAC. They played Louisiana Tech and beat them in overtime, and barely lost to Wisconsin 16-14 (lost by missing a field goal). Oh and Williams stat line for that Wisconsin game? 122 yds and a receiving touchdown on 22 touches. Utah State destroyed Toledo in their bowl game this year and Williams was voted the game MVP. He had 18 carries for 235 yards and 3 tds, to go with 2 catches for 34 yards.
According to NFL draft scout, only lost 64 yards the entire season, and averaged 6.4 yards a touch for 1,277 rushing yards.
And then Walterfootball wrote well about him in the East-West Shrine game recap.
Another player that impressed was Utah State running back Kerwynn Williams. He ran the ball pretty well even those his totals (8-28) didn't really reflect it. He also had a 38-yard kick return and some good runs.
I laugh at youtubers who like to rank draft prospects. They happened to put Williams as a second round talent. I can't guarantee it, but I am fairly certain he doesn't go in the 2nd round.
