|Williams was the Doak Walker Award winner as the nation's top running back in 2013 and finished fourth in Heisman Trophy voting after leading the nation with a Boston College-record 2,117 rushing yards. That was also the fifth-highest single-season total in FBS history. The unanimous All-American's top asset is his powerful, bruising style, though he left in the second half of the Eagles' regular-season finale at Syracuse due to a shoulder injury. Williams played in Boston College's bowl loss to Arizona, but withdrew from the Senior Bowl likely due to the same ailment, costing him another opportunity to impress scouts. Durability concerns might be minimal, however, considering his exit in the final game was the only time he missed for the Eagles despite an FBS-leading 355 carries. He also ran for a school-record 3,739 yards over 44 career games with 28 TDs. Some question how much of Williams' success was due to Boston College's run-blocking, which many considered top-notch. Though his strong build allows him to run through smaller tacklers, his 4.56 40 time at the combine validated scouts' concerns regarding his lack of explosive speed. Still, he was one of the top performers among running backs in both the 20- and 60-yard shuttle runs and ran an improved 40 at Boston College's pro day, with some scouts reportedly clocking him in the low 4.4 range. Williams gives himself extra value as a solid pass blocker, but he's an unknown as a receiver with only 10 career catches and none in 2013. He fumbled 10 times in 704 carries over his career with the Eagles. Williams is not regarded as one of the elite backs in this class but could be a steal in the early portion of the draft's final day.
