It's odd to me to see Thornton, Polk and now Williams struggle a little with route running. I am by no means thinking Williams is like Polk. Williams is a rookie. I trust he'll get it.
But these guys are behind less heralded picks like Douglas, Boutte and Chism.
It's just interesting to see 3 players get it almost immediately while others do not get it immediately (Williams) and 2 others will very likely never get it (Polk) or are almost out of the league (Thornton). If Douglas, Boutte and Chism become regulars for us, that will be something.
