This t-shirt is part of the Coach T Players' Pack, a collection of t-shirts specifically requested by the players. This Tomlin-ism refers to Coach T's response to a press conference question that went viral and turned into a meme. 

Press: "Mike, what is your reaction to potentially playing 13 games and how tough will that be physically?"

Coach T: "We do not care," (followed by a long pause).
