The guy is OBVIOUSLY doing something right. Travis is the perfect example of someone who has worked hard, achieved his personal goals, and has been the best he can be...and getting better. Not once have I heard a remark from Travis about him thinking that he is a drum god, or thinks he is the best drummer ever. In my opinion, to think that he gets too much credit is just being plain jealous. Like I said, he's obviously doing something right.
Oh, but being in the biggest modern-day punk-rock band does draw an exquisite amount of attention to the drummer. Collaborating with some of the biggest names in hip-hop also exposes him to many people who otherwise would probably never hear of him.
