I really hope Isaiah doesn't need surgery, and that Cleveland is just trying to squeeze one last asset out of Boston. However, it seems that a lot of people here just assume Isaiah will play for Boston and be 100% healthy if the deal is voided. Cleveland already proved this past season that they don't care about the regular season, so if Isaiah only needs additional time off going into the season, then what is the holdup?
Look at it from a different point of view. Before his hip injury, a trade offer of Isaiah, Crowder, and Zizic probably would have been enough for Irving, after his trade request went public. Isaiah was a top 5 MVP candidate and will only make around $6 million next season. After the hip injury, Boston is willing to throw in the possible #1 pick in the next loaded draft and it's still not good enough to get the deal done? Something is clearly wrong if neither team wants an MVP caliber player and possibly next year's #1 draft pick.
If his trade value has it rock bottom because of his hip, then shouldn't it be logical that the same concerns may effect his free agency? My only point about the surgery, was if it was inevitable during his NBA career, then why not correct it now. If not, then the hip concern will follow him for the rest of his career and will possibly effect his earning potential.
