Need to see him stack together 4 solid quarters, preferably against a good team. Also want to see him process blitzes more quickly. There were plays yesterday where he seemed to identify the hot read correctly, but then he refused to throw it there, and instead patted the ball or ran around in a panic until he was sacked. Didn't like that.
But overall, hard not to still have a "Buy" rating on the guy. When he's on, he's elite.
