 J.K. Dobbins had a somewhat surprising weigh-in at the combine, but don't let that change the way that you view him as a prospect. He was really efficient during his three years at Ohio State with a yards per carry average north of six, and he rushed for over 2,000 yards during his final season. It's hard to find that combination in this year's class, let alone in college football history. His size and strong efficiency is a lot like one of the best backs in last year's class, Daryl Henderson. Dobbins is the better prospect, but the two line up in a lot of market share-related categories, including final season yards per team play, which is one of the more predictive metrics at the running back position.
