Dude's amazing. I actually think so many people assume he's overrated that he's actually become underrated, if that makes sense.
I see what you're saying. I think people think he's overrated because his name is thrown around a lot, especially with the younger crowd. In no way do I think that's a bad thing. Dude has awesome technique, good show of dynamics (on record, live it's just a bash fest), and writes really interesting drum patterns and fills that are classic Travis. Best examples of his work are the Box Car Racer and Untitled albums. Dude KILLS those tracks.
