It's all relative. You can't intelligently comment on a manager's strategic ability without seeing a lot of his games. People who see LaRussa, Torre and others every day criticize them too.
Tito is a better strategist than Grady Little, Jimy Williams, Kevin Kennedy, Butch Hobson, Joe Morgan, John McNamara, Ralph Houk, Don Zimmer, Darrel Johnson and Eddie Kasco.
Therefore, overall, I think he's a pretty good strategist.
