WC's weakness seems to be with the bull rush, which I would suggest is probably one of the easiest weaknesses to correct. He'll likely focus on strength training in his first pro offseason, and is young and likely still physically developing.
If he was consistently getting beat clean vs pushed back into the pocket while engaged, I'd be much more worried about his development.
The fact that he seemed to further struggle against strength after a leg injury would seem to be expected.
It would seem to me that Will's struggles should be relatively easy to address in the offseason. Given his statements a few days after the SB, I would suggest he will be highly motivated to hit the weights this offseason.
Hopefully he doesn't end up on PED list or over doing it and ending up with further knee issues, etc.
In other words, I'm not all that worried about Will's further development. The footwork is there. He seems to have a good head on his shoulders. His struggles are not poor habits that need to be broken or recurring mental mistakes like jumping offsides all the time.
I was surprised to see so many on here completely looking over how Will developing in the offseason is basically guaranteed, given his specific issue this season.
Settle down fellas, the kid should be fine.
Hes know Trent Williams, but he should certainly show improvement next year.
