Both are free agents following this season. I think it's a pretty safe bet to say Wells, as a 28 y/o CF, has a better chance to stay highly productive, longer, than the 29 y/o C who has a long list of injuries and plays a position where guys break down quickly. Ack, that's the second time I've messed that up too. Barrett hasn't been catching that long, and hasn't been hurt in 3 years. I think his positional value and the fact he'll be (much) cheaper to retain than Wells wins out over being further into his prime. There's also the thing that making that trade makes it harder to improve the offense since finding a new catcher that can hit is much more difficult than upgrading CF. Barrett has to been a catcher for long. He's logged nearly as many innings there as AJP, and is at the stage of his career, nearly 6000 innings, when lots of guys start breaking down. And how can you say he hasn't been hurt in 3 years? He was hurt multiple times this year, as well as last year. He was healthy in 2004, but he's missed time in just about every other season, and he had only logged about 3000 innings behind the plate before that season. We have to stop pretending Barrett is relatively new to the catcher position. You have guys like Fisk and Rodriguez who lasted a long time as productive guys at the position, but they had the DH to rest themselves. Bench and Berra switched positions in their early 30's. The Cubs have a decision with Barrett coming very soon. And the wise one might very well be to let somebody else squeeze the last bit of juice out of his catcher's frame, or move him to another position. Barrett isn't new to the position(in hindsight I worded my post poorly), but in terms of wear and tear on the body, the fact that he wasn't exclusively a catcher coming up is a big deal. AJP had 641 minor league games, and as far as I can tell nearly all of them were at catcher(baseball cube lists that as his position). Barrett on the other hand was a SS in rookie ball, then he caught for two seasons, and then he was a "C-3B" or "3B-C" for the remainder of his minor league career. That's at least 250 fewer games at the catching position than AJP, which isn't a small thing at all.
