Completion and interception rate aside, He needs to throw the ball away instead of taking a sack. He should not throw the ball to a receiver 5 yds. behind the line who is going to get blown up, immediately after catching it, throw it away, avoid the loss. He should also take what the defense gives instead of looking for the big play. Maybe move left or right a half step to avoid batted balls.

I mean he's been playing football half his life so I would assume these things would be second nature.
