Mosul's Dolphins Question of the Week

Okay, so I am lying this week. It's not a "Dolphins" question, but there could be Dolphins answers, so I'm going to technically count it.

Last week seemed to go decently enough for a first time post. Hopefully you all enjoyed the debate, as well as thought of a few players you hadn't previously considered.

So, on to this week's question. With the Super Bowl over now, I will pose to you a two-part question that I am stealing from some pre-Super Bowl show (I can't remember which one it was, but thank you to whomever did it):

Who is your all-time Super Bowl stud and your all-time Super Bowl dud? Why?

Basically, who do you think had the all time best performance and who had the worst performance in a Super Bowl?
