Good point, it's never too early to think ahead. Orton is a decent fantasy QB, but he can't seem to win in real life. Tebow put up some nice fantasy numbers last 3 games of last year. And I believe he went 2-1? The WRs will take a bit of a hit but not too much, Lloyd still put up nice numbers with Tebow in last year.
Oh and also Eddie Royal and Demaryius Thomas coming back later might affect Decker.
