Solid QB and solid WR in Holt - but you don't have a stud RB - MJD and Jacobs should be solid, but you should have had a higher ranked RB (maybe should have done that instead of grabbing Manning). And after Holt, you don't have any depth at WR - Jackson & Glenn should should be solid, but again you should have come away with another higher ranked WR. Gates of course is solid at TE, but hopefully you didn't grab him too early.
Vinatieri and NE's D are solid, but I'm guessing you grabbed them way too early instead of getting more depth at RB & WR.
As to your bench, why did you draft an extra TE, K, and D - did you have to in your league? If not, those are wasted spots that you should have filled with RB's & WR's. And with a QB like Manning there wasn't much point picking a second QB, you could have filled that with another RB or WR. You need to dump some of these guys and grab some free agents off the waiver wire. There should be some sleeper RB's & WR's worth taking a flier on.
