Use McIntrye more. He's a bowling ball and I want to see him catch a few check downs.
Do something with the receivers where they are better. Make a more simple offense where there's more deep to intermediate routes and everybody's stretched out. Also, teach our receivers to come back to the ball and make adjustments; they wait for the ball to come to them instead of going and getting it. This lead to the Revis pick. Not sure about the pick six though, Nelson was helpless there.
I think the fact that the receivers don't come back to the ball leads to Fitz throwing the ball high, like he's trying not to under-throw it because he knows the receiver won't come back for the ball, making him overcompensate and throw high.
And lastly, make Fitz comfortable. He looks like he's forcing the ball and making dumb throws. I don't blame him when the receivers aren't getting open due to dumb routes and there's no check down option. It looked like everybody was clumped together and Jets defenders were surrounding them leading to no windows to throw too.
