I was offered Roddy and Jared Cook for Daniel Thomas and Gronkowski. I still have Gates as my other TE and Mendenhall Forte. Greene, Ridley as my other Rb's. I already have Andre and Stevie Johnson as my wr's as well. This way I will have the best WR trio in a 12 man league, so should I sacrifice my rb for it?

I think Roddy's performance will improve this year but I also think his numbers will finish well shy of last year. Not sure if you should trade or not, but I think you're forgetting Megatron in your trio argument. White's numbers are barely WR1 thus far.
