Thin is too strong a word, maybe just overexposed when asked to lead. If they were going to change this show to add, say, a Michael Holley (who is very prone to going down ratholes, btw), then I'd prefer they left Mazz and added a third over replacing Mazz. He's not great but he's not bad, stronger than I expected to be sure, but he can't make Gaspar or Adam Jones interesting, whereas Felger to some extent can make both those guys and Mazz interesting
