Brock is great. His only drawback is he is small so he gets passes tipped a lot more than bigger QBs. If the 49ers actually got a good OLine for him he would be a top 5 QB. Even Andy Reid was praising how well he reads the field and his timing. He has only played 1.5 seasons and didn't have a proper offseason last year because he was rehabbing. Shanahan trusts him. I think this year they are going to throw more. They burned out CMC, he was still great but he was wearing down come playoff time. I think they will use CMC less and throw more. 

That being said. I think you could put Cousins, Stafford or Stroud into 49ers offense and get a similar result.

I feel like Brock is so hard to evaluate, because he has the best weapons in the league and a great offensive scheme. It's obvious he's good, but I don't know if he'd be better or worse than Cousins if they swapped teams. It might just be that Jimmy G was much worse than anyone realized.
