Mostly we're OK with McCourt. There was a lot of skepticism when he took over because he didn't seem to have much money of his own to put up, and there was a concern that MLB wanted a debt-laden owner who wouldn't spend too much money. Since signing Lowe, Furcal, and Pierre, no one's really worried that he's stingy. (In Pierre's case, maybe McCourt is TOO willing to spend money.) The Ravine has also gotten a bit better, with new seats and now the parking situation seems to have gotten a bit better since the opening day issues. Concession lines are still a big problem though. After the Fox era, he would have had to really bomb to not impress us.
DePodesta is no longer the GM. Ned Colletti replaced him in spring 2006. I would say that so far Colletti's biggest error has been the Pierre signing. It's a little early to tell if the Schmidt deal will turn out to be an albatross. But most of his other moves have gone OK. We're very interested in seeing what happens at the trading deadline. My biggest worry is that at some point he'll break the bank for an overrated player like Andruw Jones or Torii Hunter. There have been rumors about maybe pursuing Scott Rolen, but considering how poorly he's been hitting, I'm not sure how good an idea that is.
I would say that Lowe has earned an extension at this point, although I'm sure his agent wants to test free agency ASAP. It will depend somewhat on the health and performance of the other pitchers. Penny was considered trade bait before the season, but he's pitched very well the last two months. There are several young guys, plus Hendrickson and Tomko, that could be starters by the end of the season. I think where Lowe goes will depend partially on how comfortable the Dodgers are with their rotation at the end of the season and on what insane amount of money it will take to sign him.
