Cardinals' Marvin Harrison Jr. appears to have made major offseason change

If Harrison had pythons like that during his rookie season last year, he did a good job of hiding them.

Those who have kept tabs on Harrison in recent months have noticed that he appears much bulkier heading into his second NFL season. The former No. 4 overall pick was recently asked about the obvious muscle he has added since the end of last season, and he pointed to his diet.

"It just happened naturally, honestly," Harrison said. "I don't know. In college I didn't eat as much probably and I started eating a little bit more and having more free time I guess, but I've been eating all the right things. Some extra protein, for sure."

Harrison is still more than two months shy of his 23rd birthday, so it is not hard to believe that his body has changed naturally. Though, it seems like he is downplaying just how much he hit the weight room this offseason.

Harrison had an up-and-down rookie season that featured only two games with more than 100 receiving yards. He finished with 62 catches for 885 yards and eight touchdowns.

While the numbers were not terrible, the Cardinals are hoping Harrison's impact will be far greater in his second NFL season. Perhaps all the bulking the former Buckeye has done will help.
