I accept this trade.
I feel that Backus is quite old and thus his value is diminished. Best on Madden is a very good player and picks up the slack in 'adjusted value' from Backus.
Cobb and House are very nice players who can match Best's value. I do not see Backus as a factor in this trade due to your explanation as well as his age, which negates his positional value and OVR.
bla bla bla hope that sounded like i know what i'm doing.
this trade gets my seal of approval, now for the next guys! haha
