Then why'd we get rid of Patterson? b/c he couldn't get on base. what does that have to do with speed not slumping? i realize you can't use speed w/o getting on base, but that's a separate argument from speed not slumping. No, it's exactly the argument. The saying "Speed doesn't slump" isn't referring to basestealing, it's referring to guys not going into hitting slumps because they can use their speed when they struggle. Unfortunately, speed does slump, because slumping rarely has anything to do with speed. Corey Patterson has a ton of speed and slumped terribly because he couldn't make contact and when he did he hit it straight in the air. Neifi Perez has some speed, and he can slump terribly because all he does is weakly hit groundballs. It sounds nice to say "Speed doesn't slump", but it's not true. If you can't hit you can't hit(whether it's your true ability or a bad stretch), and occasionally beating out an occasional chopper or bunt doesn't change that.
