Jamaal Williams

Former Boston College running back A.J. Dillon rushed for 1,685 yards and 14 touchdowns in his junior season, and racked up 4,618 yards from scrimmage and 40 total touchdowns in three years. While he worked mainly as the No. 3 running back when the Packers hit the practice field, he was the player everyone was talking about -- mostly just because of how he looked physically.

"He has got some massive legs," Packers head coach Matt LaFleur said, via Rob Demovsky of ESPN. "That's something we talked about with our staff, we have not seen a running back built like that -- not in my career, that I've been around."

The story added CBS NFL Draft writer Chris Trapasso believes that Dillon is a player who will come in and make an immediate impact. He even thinks he could replace Williams this year. Williams recorded over 700 yards of total offense last year and added six TDs, so it's a situation to monitor, perhaps especially for Jones owners looking to handcuff him later in drafts.
