They covered this topic, and not to steal the thunder or anything, but they made some good points on it, like with Buchner they have to trust the the WR is going to be where he is supposed to be, and pretty much the same with Pyne. Salerno has been here for awhile and knows the playbook well.
He didn't go in motion as he should have on a play, which turned into a bad play. He hasn't been on the field since.
I can't say if the playbook is too complicated, but in my opinion they should be able to have a set of plays that he should be learning, at one position, preferably in order to give Lenzy some rest. I don't know why a wideout has to learn the whole playbook in order to see the field when you can create a package of plays for a QB to see the field.
If others have more insight into why that is not possible I'd like to hear it.
I'm hoping the bye week got him some more practice and better acclimated with the playbook.
