I love Draft Daddy and wish they'd start a message board. I think they might be worrying- since they are already "a bit" un-pc (they're one of the few mainstream sites that will even "mention" the "OBVIOUS" double standards)- that if they started a message board it might draw some real racists in.
Of course, they're not racist in the least. In some ways they're even a little pro-black athlete, but they at least have the backbone to be honest about the extreme injustice once in a while even though it could backfire on them with the Luginbill/CaucasianRivals media lurking.
