Trade Help Plz ASAP!!

[BabyArm]

I have been struggling with this question for quite some time, I traded for arian foster a few weeks back and he's been spectacular, putting up 20+ pts against Jets D... With the trade deadline looming, and other positions looking weak, do I trade him away or let him carry me to the superbowl? Here's my problem, my WR2 spot is no good, I have Floyd and Ocho battling for the job right now and I dont like either really, Floyd had only two catches last weekend and thats without Vjax... and Ocho is very capable of putting up a bagel without any notice... I've got someone on the hook willing to give me darren mcfadden and brandon lloyd for arian foster and jacob tamme...

Plus
Run DMC and brandon lloyd have awesome matchups the rest of the way
Floyd --> Lloyd is a huge upgrade
Foster --> DMC not a huge downgrade
Im a pats fan so I can live with hernandez as my TE

Minus
Arian Foster is the best player in fantasy... Hes gotten me this far and I feel loyal
J. Tamme has huge upside and gets a ton of receptions but has not lived up to the hype besides wk8-9

I appreciate your input!
