I think it more likely that Humphries comes back on a one year $8 million deal than it is that Bradley would come back on a 1 year $4 million deal.
Getting Hump for one year on an overpay makes a ton of sense, IMHO. He gets to mentor the young guys some more. He gets his really good pay day that few other, if any, teams will give him. The C's get him off the books before the season they are really looking to make ways, the 2015 off season. Hump, I think, gets a no trade clause and so if he wants, he's guaranteed to be here all next year if he likes Boston that much.
Win-win as I see it as I expect Bass is gone this off season.
