Onto the 2010 Running Backs – (RB) Rankings \u2013 <\/strong><\/h3>\nC.J. SPILLER, Clemson<\/strong><\/p>\n <\/strong>Spiller is a home-run threat of the first order. He\u2019s probably the most explosive offensive player in this draft. ACC fans didn\u2019t see it for long, as Spiller spent a few years on the bench at Clemson behind James Davis, only getting mop-up carries. However, Spiller has versatility because he could return kicks and punts as well as run and catch the ball. Spiller is an instinctive back with speed and is surprisingly good at breaking tackles for his size of 5\u201d11, 195. In a league that is evolving to demand a stable of two or three contributing backs, Spiller projects as an ideal change-of-pace No. 2 back. He should go in the mid-to-late first round.<\/p>\nRYAN MATHEWS, Fresno State<\/strong><\/p>\n <\/strong>Mathews, who plays in the seldom-publicized WAC for the Bulldogs, has vaulted himself with a fantastic Combine. He has nice size at 6\u201d0, 218 lbs, yet clocked an admirable 4.45 forty and showed off a 36-inch vertical. He could shoulder 20+ carries a game and does the little things well; blocking and catching the ball with effort. He\u2019s a one-cut style of runner that won\u2019t dance around in the backfield; in other words, he\u2019s the anti-Reggie Bush. That will be refreshing for coaches to see and Mathews could be off the board in the late first round \u2013 he looks like a nice fit for San Diego with the 28th<\/sup> pick.<\/p>\nJAHVID BEST, California<\/strong><\/p>\nBest is another dynamic runner in the mold of C.J. Spiller. He has elite athleticism and actually clocked the fastest forty-time at the Combine, with a blistering 4.35. He\u2019s 5\u201d10 and a hair under 200 lbs; his numbers dress him up nicely. However, Best has been described as a great \u2018runner of the football,\u2019 but not necessarily a great running back. Why? Though fast and explosive, he doesn\u2019t run the ball with much aggression and is downright weak in pass protection. Coaches at Cal would take Best off the field on obvious passing downs because they didn\u2019t trust him. Yet, his athleticism will lure some team likely in the second round.
