Yes he's p---ed. I think he and not the doctors was the belated cause of the Cavs' buyer's remorse and unprofessional wavering, he wanted them to back out or get more, and they didn't, and now he's stuck carrying the team while Isaiah recuperates, hoping Isaiah comes back at full strength, wanting the Cavs to use the Brooklyn pick in GFIN mode but they won't, and watching his former sidekick kick ass on the conference rivals. He's gone at the end of the year, and Ainge cemented that with this trade. Ainge is a genius.
