I don't like Doc. Didn't want to teach and his coaching was suspect. Only won 1 title with 3 hall of famers.
I never looked at it that Doc didn't want to teach --but that he agreed with PP and KG not Danny and wanted another year of pursuing the Title with his veterans. I still consider what Danny did to Paul as disloyal to a player who gave his all for the franchise and wanted, and in my opinion, had earned the right to retire a Celtic. Water under the bridge but I do not blame Doc but blame Danny- I would have liked to see what another year of a healthy KG, PP and Rajon core could have brought.
As Moranis (TP) has said, they had a last shot and showed their tanks were half-empty. They needed to be the supporting cast they were in Brooklyn, not the main options they would have been here. That said, the events that happened for them are not our fault.
If Danny would have done what you say, we wouldn't have Jaylen Brown or a good shot to Fultz/Ball this summer and a good pick in 2018. Or a good trade with the picks. With Pierce and Garnett retiring with us, the rebuild now would be starting.
This is business, and Danny understood it very well. To get emotional, watch a Zeffirelli film.
