It's easy to ridicule Gabe Kapler after that very conspicuous bonehead maneuver but many people have been very high on Kapler's potential to manage baseball.
The Sox, if anyone recalls, wanted to groom him as a manager by asking him to manage Greenville. Of course that is when he got the itch to play again which was in my view, misguided.
So make fun of him all you want. He may fail. But he was very highly regarded prior to his flub at the mound.
