It's fair, and I see why you'd consider it. I drafted Holmes on all my squads - really thought he looked like a 70/1000/8 guy you could get several rounds later than the rest of the WRs like that were going for. So far I've been wrong. I think he and Harvin are about on the same level. For my sake, I hope you're right about Holmes though.
So for me the trade comes down to Turner/McGahee for Foster. Very fair ... could pay off for you. If you had Tate, it would be a no-brainer. The loss of McGahee may hurt more than you think. He seems pretty solidly Denver's RB1 now. In fact, you should be starting him in your flex (not Harvin). Though if Tebow becomes the starter, McGahee stands to lose a lot of value (since Tebow, like Newton, will steal GL rushes). And Turner's not without his own injury issues.
I guess if it were me I'd do that deal. Foster has his hammy issues, but it's not like Turner doesn't have his own injury baggage. McGahee's value could deflate in an instant (either Tebow starts, or they start playing Moreno more - neither of which would surprise me in the least).
