sorry, I don't totallya gree on smith. he maybe talented, has nasty demeanor, but he is raw, his technique needs work and he had 16 penalties IN COLLEGE last year in 12 games playing against inferior competition. we complained about Williams, me included and now we get a guy who is potentially more penalty prone....he is a project since his technique work will take a couple of year at least.
I don't dislike Williams, but he is a rookie second rounder, with some predicting he is a third rounder..... its DE in the NFL. Parsons was special. top 12 pick, Williams is not special and he will share time, not sure how well he will do. it takes DE a couple of years to adjust. I doubt if lightning strike twice two years in a row.
I think if tolbert gets 20-30 catches it would be nice, but probably because he is 4th or 5th option and he will benefit from that. he is not going to take pressure off of CD and Gallup anytime soon. so no immediate help.
I think the 4th rd TE is a blocking TE, so as you said he may help in the run game.
I am not as impressed. they have potential, but not immediate dividends.
