Historically, it's tougher for the physical WRs to adapt to NFL than it is for the quick WRs. And BTW a ton of college DBs tried to be physical with Smith at the line and then abandoned the strategy when he kept getting by them. The oft-repeated worry that Smith will get "man-handled" by DBs is based on nothing more than his weight and completely debunked by the film.I also think Chase wouldn't get manhandled by DBs like Smith would at the NFL level.
