if you can get this deal, i would go for it.
megatron (whom i just dealt in one of my leagues) will never put up the numbers he should with a below average QB.
Arian Foster = 1st rounder next year. The guy is legit. Im so stoked i dealt Will SMith (DL) for him prior to the season starting.
Rodgers for Schaub is a close tradeoff, but with you getting Steve Smith too, i think this is a great deal for you.
