Look at the major TV appearances, the movies, the actors/directors/cinematographers he's worked with! The association with David Mamet, the Broadway experience, the off broadway and regional credits are all signs of an actor with chops. It's amazing that this actor is not a weekly entity on TV. Networks wake-up! You have a gem waiting to be placed in the right setting and his fans want to see him.
As a young aspiring actor myself, this is the kind of guy you pay attention to and say to yourself, "When I grow up I'd like to be doing that."
