Oh, I don't have any illusion that he would bring a bona fide pitcher by himself. I suspect that if we're going to get a real pitcher, it's going to involve giving up a couple guys that hurt a bit.
Anyway, Kemp has essentially *no* power, and isn't really projected to develop any, as far as I know. I'd like to get more pop out of my left fielder than that. A platoon in CF plus the occasional start at 2B might work ok. My understanding is that he doesn't have the arm to really be a general utility guy (i.e., you wouldn't want to put him at 3B or SS).
Personally I don't care what position a leadoff guy plays if he's good. It also helps if you're getting power from other spots in your lineup, and the Astros are getting HR from every position at 2B this year - and even there, Altuve might give you 10 or so.
Back to the trading point, what I meant was I think most clubs would view Kemp as almost a throw-in, and my suspicion is the Astros value him a lot higher than that.
Interestingly enough, Kemp really struggled vs. LHP last year, but has even splits this year so far. Wonder if he changed anything.
