I don't know about the Hall but he never learned to bunt. For someone with speed, I was appalled that he could not lay down a bunt. The straw that broke the camel's back for me was the 2004 ALCS against NYY. Game 4 or 5, extra innings, situation was ripe for a bunt and he looked like an infant attempting to lay one down. I am amazed sometimes at pro's in this day that never attempt to learn the finer points of the game.
