Way to go, Cavs. This guy and Jeff Green will absolutely be the keys to closing the gap on the Warriors. No wonder Lebron wants out after next season. Going into a critical offseason in win now mode, and Gilbert not only lets his GM walk but he doesn't get anyone hired in time for the draft or the opening round of free agency.
Cleveland is still the favorite in the East, but as currently configured they're still nowhere near good enough to overtake Golden State.
While your right that the Cav's haven't improved enough to overtake GSW there isn't a lot they could really do to improve. Due to the contracts of Lebron, Kyrie, K-Love, Trystian, JR, and lesser contracts to Shumpert Kover, fry they're caped out going into the offseason, The only move they could have done was to get improve PG-13 and once Griffen left that wasn't going to happen. I don't' want to kill their offseason when they don't have much of chance to improve and are paying 70 mill + in tax to the league.
It isn't a sexy off season but Ossipi, Korver, and Jeff Green are possible upgrades on the bottom of the roster. Granted Green has been a tease in the past and Ossipi may or may not translate but both have talent and won't need to play big roles if they aren't playing well. They will also be the destination for buyout guys during the season to fill some holes.
In the end Cleveland won the offseason due to the East teams not getting appreciatively better, get to the finals and let the chips land as they will.
