Steve Smith is 20 pounds heavier than Austin. He was 10 punds heavier than him coming out of college too. Not to mention Austin doesn't have nearly as much Strength as Smith does, and is unlikely he can gain weight without losing speed.
So? Does that mean he can't play? I bet if you asked steve himself, if he thought Tavon was to small to play in the NFL, he'd probably just laugh.
Also adding 10lbs of muscle wont be hard to do nor will it slow him down. Still think its funny that Panther fans dislike a guy because he's "too small".
