I agree. Probably his best performance yet.
IMO, there's one thing that separates Roger Maltbie from the rest, besides his obvious experience. He doesn't make a habit of competing for airtime, and when he does contribute it's usually something significant, he generally keeps his commentary short and to the point.
His insight as a caddie for 20+ years with Phil gives him perhaps an even deeper quality of insight, especially considering that he's generally well-liked and respected by all of the players, including the younger ones.
