The guy I want more than anything is Matt Barnes... This team needs some attitude and with the rotating door of LeBron's backup continuing next off-season (RJ being a free agent), I would do everything to get him here... He's an inefficient 3&D guy but he's being brought in more for just his strictly on-court play...
The intriguing part of the off-season will come with what the Cavs do with Mozgov... His play this off-season has severely hurt his value but I'm sure some team is still going to want to pay him... The best case scenario, in my mind, is to try to re-sign Mozgov to a prove-it deal but there seems to be a bit too much water under the bridge for that to happen.. For the type of money he'd want, I'd rather allocate that to re-signing Delly and finding a new center...
For what the Cavs need, I think there are a lot of intriguing options on the free agent market... To me, the Cavs need to find a mobile, rim protecting big who can start and play around 20 minutes a game... With Love, TT, Frye and Bron playing small ball PF, I don't think they need a huge investment at the center position... Just someone who can take the burden of banging off TT and be a rim deterrent..
For that, my two faves are Bismack Biyombo and Ian Manhinmi... Manhinmi might be getting a pretty good raise with how he's playing but could be an option...
Joakim Noah, Nene and Roy Hibbert all go under the "vets looking to ring chase" group, that is all dependent on if they want to come here and how well the Cavs can recruit...
Festus Ezeli and Miles Plumlee are both interesting because they're young and experience, but they fall into the RFA group meaning it'll be a little harder to pry them away...
