Williams is being hailed as an All-American candidate after gaining 1,266 yards from scrimmage in 2012. But while those statistics aren't undeserved, per se, they might be slightly misleading.

After transferring to Norman from Arizona Western College (JUCO), Williams had to fight his way past Dominique Whaley and Brennan Clay on the Sooners depth chart. But in time, he endeared himself to head coach Bob Stoops, especially with his big frame and ability to help as a pass-blocker.

But therein lies the deception of Williams' talent. He's really only a threat on passing downs, which makes him a good fit in Oklahoma's system but a tad overrated as a player and prospect.

According to Football Outsiders' S&P rankings, Oklahoma was the seventh-best team in college football on passing downs last year. (Passing downs being defined as: second down with eight or more yards to go or third or fourth down with five or more yards to go.) By contrast, the Sooners were just 43rd in the nation on standard downs, below the likes of Army, California and Central Florida.

No other team among the top 22 offenses had a lower efficiency on standard downs, the snaps where your running back is of utmost importance. Those are the downs where a running back is supposed to move the chains, to keep you from needing a passing down to begin with. Williams did not prove to be that guy.

There's also the issue of competition. Williams only topped 50 rushing yards in just six games last year, and all but one of those (at TCU) came against sub-quality defenses. UTEP and Florida A&M are small-conference schools, while Texas, Baylor and West Virginia allowed an average of 177 rushing yards per game.

Williams is a serviceable halfback in a system tailored to his strengths. But an All-America candidate he is not.
