Agree.
I see Palmer taking over more of the role they hoped Cooper would fill. As the roster sits today, Shavers would be more in line to take over the Hollins role especially on STs. I expect more to be added, of course.
I do think Bosa will be an impact player. He has a ONE year deal. It's a prove it year for him and he's acknowledged as much. He's going to be motivated to not only produce, but stay on the field through some of the nagging things he say out through in LA.
Also, imagine going from playing in front of perhaps the most laid back fanbase in the NFL to our rabid pack of table smashing drunken idiot fanbase. Guy is gonna feed off our fans.
