I've got Cousins & Locker as my only QB's, so it's definitely a position of need going forward. I'm pretty healthy with WR's in Dez Bryant, Antonio Brown, Percy Harvin (and Brian Quick). I see managers who can trade away Rivers/Newton/Wilson. Is trading Harvin for any of those 3 QB's (1 for 1) a good trade for me?
I'd probably just hang on to Harvin. I think you can get by with Cousins and Locker in the short term, and if Cousins doesn't turn into a good player, I think this trade offer will still be available for you later.
