You think the Rangers would let him go?
I'm sure they'll try to keep him, but there's sure to be a few teams that come in offers that will be batshit crazy in terms of years and/or dollars, in which case, I don't know how hard the Rangers try to meet or beat. The guy's magic when he's healthy, but he's also streaky, and he's prone to injuries, some major, some not. And he's not a kid, so a 7-10 year deal at big bucks a la Pujols is not a good bet.
OTOH, he's one of the best, if not the best, talents in the game right now, and is definitely an impact player. A nice crazy-money five, or even six, year deal is something I don't think the Rangers would balk at, not at all. But you know that somebody's going to offer 7 or more years at even crazier money, and that might be the point when the Rangers tell him "thank you for everything" and start moving on. Josh gonna make the best deal for Josh, and that's how it should be, dammit. And dammit....
That's gonna suck, but life goes on, and as long as the system is developing players like Leonys Marin & Mike Olt (and as long as they keep developing themselves), you just gotta hope that good business sense and potential talent don't cross each other up.
One team that would be quite doubtful for Hamilton is the Yanks. They're trying to get under $189mil for payroll to escape the onerous luxury tax due to kick in in 2014 and they have Granderson & Cano as free agents prior to 2014. There's even scuttlebut that the Yanks may have to let Granderson or Cano walk to keep the payroll under the $189mil.
Granderson maybe, but no way the Yanks let Cano go.
