It's a good observation. Smaller is quicker, generally. Most of the DBs in the league are under 6', are fast and can turn on a dime (they just can't catch, that's why they're DBs). So you make sense there. But on the other hand, a big target over the middle that can jump and take a hit can help, too. We call most of those guys tight ends, though. Remember, the slot doesn't have to run the post, he's looking for the sticks or near them on most 3rd down routes. It's really going to depend on the talent of the WR, too, size or no size.
The main point is Az is afraid to take the hit, or at least he was in Detroit. That, and the drops. Those are both bad qualities in a slot. But like I said, when he catches it, he's gonna make a play. Good luck with your draft. I'll take anything BUT a wide receiver.
