The problem with a pitcher as color is that pitching tends to be only thing they talk about. Petry tends to this side - plus it's disappointing he doesn't fix his verbal 'ya know' tic. It's not that hard to do if you are at all serious about doing the job well. Morris, for all his other faults did at least talk about position play a little. Catcher - a la Jim Price - is probably the best you can do if it's going to be an ex-player. Close to the pitching but still has a hitter's perspective.
