I read a similar article on Harrell at the JS Online. Apparently, he's now 320 with 305 pounds being the goal. Said he's had "too much bbq." Seems like he could lose that with camp, but maybe he'll add even more on his upcoming trip to Jamaica.
According to Harrell and MM, the main goal is for him just to stay healthy for a whole season. Sounds like a good goal.
The best thing I saw in the articles was the fact that at least Harrell himself realizes that he hasn't done much, yet, in his time in Green Bay, and acknowledges that this upcoming season is a critical one for him.
For Harrell, it seems like a matter of "stay tuned." One of the articles (or somewhere) had him "penciled in as a started at DE." No doubt, TC will be big for him, as it is for so many.
