Actually count me as one who thinks the Monforts might just give Arenado what it will take to sign him long-term. The Rockies have always been about marketing their one or two big stars, and they've often paid handsomely to keep them: Walker, Helton, Tulo, Cargo. I don't want to say I expect Arenado to sign with the Rockies, but I can definitely see it happening. 

I agree about DJ/Rogers. DJ is an excellent 2B and a pretty good hitter (although I do think he's a bit overrated with the bat), but he's entering his 30s next year and 2B is a spot where they have a young and cost-controlled player coming up to play that position, and so letting DJ go is probably the smart move for the team. It's essentially the same thing with Cargo, too... the Rockies can afford one, maybe two star players, and the rest of the roster will need to be relatively young and affordable. So they need to pick and choose those stars carefully.
