I've been told he was offered more by Florida, although this wasn't about the money or, from what I've been told, the Panthers. Monty simply looked at the roster and didn't see himself really fitting in. Monty was shuffled around last year, from the checking/energy forward lines to being on the third defensive pairing.
Good luck to Monty out west. He's going to dig it out there. I know a cool place in Garden Grove -- not far from the Pond.
