Wannstedt still has to take blame. He was given one of the most talented defenses in the league, a stud RB like Ricky, a competent set of receivers and a decent QB, yet he couldn't take it to the next level like some of the better coached teams.
Could Miami use better parts? Definitely, but up until this year, they had some of the better talent in the league, but failed to capitalize. Blame lies all over for this franchise, from Ricky all the way up to management.
