>>15797080He's a good coach.
He understands the mental aspect of the game better than most coaches in my opinion. He really has an impact on player discipline and good hitting philosophy.
It was a great hire for LaRussa. Mark reminds me a lot like Dave Duncan, actually. He can make a player with good talent focus on simple goals and can break the game down. He can't teach magic hitting mechanics, but at the big league level that isn't what is needed.
