Nah. If he's going to get high, he's getting high with his crew. I'm not so worried about the drugs. They only test you for recreational drugs once a year. As long as he doesn't get stuck in the program, I think he'll be fine. You have to be really dumb to fail that one test. This guy seems alot smarter than that. The main thing to worry about is his effort. Worst case, I think he disappears for some games. But I get the feeling he'll show up for the playoffs when it counts.
They showed a play on ESPN where they had him lined up as an h-back, caught a pass downfield, and ran 30 or 40 yards for the TD. When you watch him run, he doesn't look like a guy that weighs 290.
