In terms of buttfumble, I think he really isn't very good. His "success" was mostly based on his running game and defense and he really didn't have to do much to win games. Junc might be happy with him but I really don't think many others are. Having said that - what the whole front office did in terms of bringing in Tebow (this isn't a bash on him) was guaranteed to be a distraction to a QB that already was in trouble. Not genius to say the least. Is it his fault that buttfumble isn't good? No. Did he make buttfumble even worse. Sure looks like it to me.
I can't imagine if I was a fan of any team and I heard that my team named Tony Sparano as a coach - I think "throw up in my mouth" might be one real possibility!
