Not sure he gets "better" but I don't see his value changing a lot. I see him as a top 5 QB if he stays healthy. He just does too many things well to take them all away. That said, if you have another plan at QB and can get someone to go crazy over him, anyone can be had for a price. Just not sure I could risk having to watch him blow up against me for 10 years if I dealth him in a dynasty league.
