Maybe. But Garappolo didn't look this good here, either.In Jimmy's two healthy seasons, he went to a Super Bowl and NFC Championship Game.
If Purdy played in Oakland under McDaniels, he would not look like this.
He fits the scheme of what the offensive direction needs. But he's uniquiely suited for that scheme as well. He can be a good fit offensively without it being simply that he is a fit that makes him good.
