Buck would leave an obviously ineffective pitcher in way too long. A guy who's missing out of the zone with every pitch, a guy who's walking them, and getting hit hard every time he throws a strike, with the O's up by 5 runs, would be left in until the opposition tied the game or the pitcher threw to their pitch count, which was usually around 100+ pitches.
Hyde is the complete and polar opposite. He pulls effective pitchers who aren't even at a high pitch count, just because they gave up a clean ground ball single. He does it whether we're up by 1 run or 7 runs. Guaranteed, no one will pitch a CG SO, no-hitter or perfect game under Hyde. He won't give them a chance.
Call me crazy, but I feel like the "right" way to manage pitchers is somewhere in the middle of the Buck and Hyde extremes. Hyde's way babies the starters, even good ones who are perfectly able to continue, at the expense of destroying our pen's long-term viability. Buck's way vastly hurt our win chance by keeping a gassed or command-challenged pitcher in for 20+ pitches too long, usually until the bases were loaded or worse.
