This offseason will be key for LeBron and Cleveland chances to keep him. Zydrunas and Verajao have player options, and I think Verajao will surely opt-out. Will Cleveland give him the money? Will they let him walk, while still being over the cap?
Depending on how the Verajao situation goes, the Cavs could see quite a decrease in depth and talent surrounding LeBron, plus not have the financial resources to bring in better talent to keep LeBron interested.
If I were the Cavs, I'd try to make some 1-year deals with some of their players that are free-agents, even if they overpay, and try to make some good deals during the season.
