I punted TE position, but what do you think otherwise?

2 QB full PPR league with a bunch of sharks that know their stuff.

QB - Luck, Dalton, with Bradford on Bench
RB - Freeman, Howard, Montgomery with West, Kamara, and Stewart on bench
WR- Jordy, Crabtree, Diggs with Crowder, Moncrief, Ginn Jr on bench
TE - Witten (yikes)
Def - streaming. Picked up Colts, but have a bid in for Buffalo as they play the Jets and the Jets might actually be the first team in league history to have negative points at the end of a game…

Where can I improve? Tight end is a given…but nobody has told Jason Witten that he is old and busted. He might be pretty safe in PPR…
