Seahawks fans form 'U Mad Bro?' t-shirt formation at Super Bowl

One group of Seahawks fans has arrived at University of Phoenix Stadium in a t-shirt formation that spells out the well-known Richard Sherman burn, "U Mad Bro?"

It's unlikely that Richard Sherman won't be able to trash talk for himself both before, during and after Super Bowl XLIX Sunday.

But in case he can't, one group of Seahawks fans has arrived at University of Phoenix Stadium in a t-shirt formation that spells out Sherman's well-known burn, "U Mad Bro?" 

Sherman famously asked New England Patriots' quarterback Tom Brady after a regular season game in 2012 if he was mad after he walked off the field without addressing Sherman.

Brady had allegedly boasted to Sherman before the game that New England would win. The Patriots lost that game 24-23. That was the last time two teams met. 

Here is Sherman explaining his version of the origins of the original 'U Mad Bro?' questioning.
