I wonder if this is before of after the combine. If this is before the combine test then I would think it's probably pretty common practice for the agents to give the players a heads up to stop smoking 6 weeks before the combine and that it's time to lay off the weed for good.. college days are over talk. So that could have happened and since he did smoke in school someone could ask him if he is nervous, but since he stopped he had no concerns about failing, but no one wants to fail so might as well do anything you can think of that might help, like a sauna. Even if you haven't smoked in over a month or whatever. And since he did smoke in college, like every kid that smokes if there is a chance to go into a virtual candy store and see something you never saw before it would be pretty hard to resist going and looking at all the different varieties that are sold. I think the publicity of that visit helped him realize that all eyes are on him and he can't get away with things like he would in college. Will he be able to stay away from weed at least to the point he does not get caught, he seems smart enough and cares enough about football that I think he has a good chance to do that. I don't think he is any different than 85% of the players that come into the league from big programs. Most can do what they need to do to play in the league, others have a harder time like Gregory.
