Last week, Penn State’s Aaron Maybin raised eyebrows at his Pro Day with a performance fueled by a stunning, “you-wouldn’t-like-me-when-I’m-angry” increase in his physique. North Carolina’s Hakeem Nicks also showed off a new body last week -- but not in a good way. Since tweaking his hamstring at the Scouting Combine, Nicks had been unable to work out. And, as a result, he gained roughly 15 pounds in three weeks. (NFL.com has the number as 14; we’ve heard that he gained 16 pounds.) As one scout who attended the session opined: “He looked like a fat tight end not a lean receiver. . . . He’s got to have a weight problem. This is the most important few months of his life and he gains a ton of weight. I don’t get it. Many scouts and coaches went away very disappointed.” That said, we’re told that Nicks already has shed much of the weight, and that he’ll be working out privately for the Bears and the Dolphins.
