I'd add Russel WIlson to that list. They already talking about dumbing down the playcalls for him. I would still put Watson first. Especially considering the other things given up for him. Jones contract they can get out of. Watson is tied to that club. They are still kicking the can down the road on him.
On another note, considering the GIants lack of talent, SF wasn't really thhhhhaaaaaaaaaaat impressive. Not as impressive as they should have been anyways.
It's not really what they need to do against Purdy. It's they are not getting to or not tackling the playmakers. Most of Purdys passes were chump yards.
