"In general, the concept that players play their best in the last year of their contract is probably overblown. There's no doubt, though, that we've seen our fair share of guys with dollar signs in their eyes go out and put up big and sometimes career-best seasons.

With that in mind, it's at least worth being aware of the noteworthy potential free agents for next offseason. Here they are:

Catchers

Chris Iannetta, Angels (club option) – Iannetta can void the Halos' option for 2013 since he was traded. Obviously leaving Coors Field for Angel Stadium isn't great news for the 28-year-old in his walk year, but he'll also be the unquestioned full-time catcher in Anaheim, something he wasn't for long chunks of time in Colorado.

Russell Martin, Yankees – Once appearing destined for stardom earlier in his career, Martin was great for two of six months last season in New York but terrible the other four months. He'll turn just 29 next month, but it's unlikely he'll net a whole lot even if he does get a multi-year deal next offseason.

Brian McCann (club option), Braves – Barring a major injury, the Braves seem likely to exercise McCann's $13 million option for 2013.

Miguel Montero, Diamondbacks – The D'Backs have talked extension with Montero's representatives, and although there doesn't seem to be a lot of momentum for a deal right now, it seems likely one will get done eventually.

Mike Napoli, Rangers – Likely because they're focused on other contract matters, the Rangers decided not to pursue and extension with Napoli this offseason. Barring midseason talks, he'll hit free agency next winter, and if he has another year even close to the one he had in 2011, he'll be in line to strike it rich.
