Need some advise about my team

[godd2]

I picked 4th in a 10team standard scoring keeper league. Not real happy with my Def or TE but there was a run on the top teams before it got back to me so i just waited until the last few rounds to get them.

QB: rivers (keeper)
RB: Mendenhall, Greene, Jacobs, woodhead, fred jackson, helu
WR: wallace (keeper), Mike williams, Mike Thomas, amendola, greg little
TE: gronkowski (may go get kellen winslow or tony gonzalez)
Def: San Diego (maybe dallas of giants better?)
K: josh brown

any advise would be appreciated
