the thing is, if you are going to build a lineup with speed and contact skills, it can't have terrible holes in it, you need everyone to to at least average OBP so you have a decent chance of stringing things together once in a while. If you score using a lot of power, that's less important. If you look at the Tigers now, you see Keith and Perez with low K, potential for decent averages, if they develop a little more walk skill they could play on a team like that. And if Parker could hit for a little more average, his walk rate is usually decent and he has speed so there is another guy that moves you in that direction - if he can hit enough.
