Here's some info from Drew on his visit with the Falcons:
The Falcons were the first team I worked out with. They run the same type of offense that we run at UCLA, so I was already familiar with the terminology. In football, if you can speak the same language on Day 1, you're already ahead of the game. I wouldn't have to learn a new system at all and could just concentrate on adjusting to the speed of the game and the other nuances of the NFL.
The Falcons had me catch a lot of passes, as opposed to just doing run routes. What was funny was that they stood about 3 yards from me and just drilled the ball into me. I would stand facing the coach and he'd throw it. Or I'd have my back to him and turn around and he'd fire it in to me. I guess Michael Vick throws the ball pretty hard so they were trying to duplicate that. We also ran a bunch of running plays and protections. It was interesting and I had a good time with them. http://www.nfl.com/draft/story/9363659
