6 Rush TDs with the Dolphins
6 Rush TDs in a game with the Dolphins (non co-op)

WTF? I get the "challenge" of playing as the worst team in the legue and somehow getting 6 rushing TDs. I'm sure it's an epic challenge to be sure (Dolphins suck!)

But, there is no way I'm going to play as the dolphins...so IMO this is an unachieveable achievement :)
