I won't give Wren and company a total walk on Uggla because, as you say, it was plausible that he would remain somewhat productive. My issue is you don't give a guy with as obviously limited athletic skills as Uggla a long-term deal after age 30. Maybe if you're in the AL where he could DH, but the guy is a one-position player (and terrible at the one position he can play) who has a slider-speed bat. Only thing that really buffered that is that he could draw walks and hit mistakes. Now he can't hit mistakes, so he doesn't draw walks because the pitchers don't have to nibble on him.
I would have been fine with Upton at 4 years at $12 million (or pretty much what Bourn got from the Indians), but Wren bid against himself. In fairness, we did need a CF.
But, to me, the bottom line is that the core group is Freeman, Heyward, and Upton the Younger (again, in fairness he was acquired after Wren handed out the candy to his older brother and Uggla). Add to that a good fielding shortstop who is signed to a reasonable contract and you fill in the slots around that. Gattis has been a surprise (although I worry about his longterm durability). Chris Johnson was a pleasant surprise last year and a horrible disappointment this year and I think the extension was a mistake because, again, he's not that important to the core of the team. I think you could get by with a cheap platoon at 3B with guys who would complement the core more appropriately. I like La Stella as well.
But the simple fact is we are paying too much for guys who do too little.
PS--Yes, you're right. I can't remember if the extension was simultaneous with the trade, but Wren's logic was "I'm not going to give up two guys for a rental." My point is that if you're dealing with a tight budget from the top (which we supposedly were when Uggla was acquired), the logic should have been a 180 from what Wren thought. You have a core of guys coming up from the minors and you acquire a guy like Uggla for a year as a bridge to that core. I don't think Billy Beane walks on water, but those are the kind of moves he's made that have met with some success in Oakland. You roll the dice on a guy for a year and let him walk (or move him if and when you out of contention).
