I think there will be incremental improvements each game, but after now watching the first two games, I'm starting to think doing nothing and sending DaAaron home for the rest of the season may have been a better choice. Ellis is an easy fit with the other starters and we already know its been effective. There aren't many games left in the season and even a small losing streak is going to sink us below the play-in seeding. It is going to take some time to incorporate a player like Lavine into this starting lineup. Overlapping skillsets, unique nature of playing with Domas, defensive deficiencies, etc.
I would still give the trade a B as far as talent back. Looking at what the bulls got in the deal, I don't think that's a better alternative (would you really rather have Zach Lavine or Collins, Jones and the Bulls lottery protected pick this year...) and clearly the Spurs weren't desperate enough to make it happen with higher value picks or young players.
However, I do feel like the transition period might just cost us the season...which then has cascading affects. Monte/Doug probably gone in the offseason, and who knows how Domas, Demar and Lavine will feel individually about their future here. Not trying to be overly reactionary here, and I still like the concept of Lavine here, but it's not a seamless fit with this team that happens overnight. Hoping they now get a day of practice together and then come out with a better showing against the Pels to instill some confidence. They need to stay afloat until the all star break.
