Still think would have been decent trade even with McCoy hurt now. That's why if you have a golden offer accept right away. Ppl only pull the deal when they realize they're not winning. If you're on Yahoo just look at what trade evaluator says (not perfect but gives an idea at what updated lineup is like)

Last 3 weeks (0.2 PPR)
Manning 44 pts
RG3 45 pts (30 this week)
McCoy 35 pts (+10 in full PPR)
Murray 0

That's plus 34 points. And Freeman tops them all with 49 pts.
