I'd like to see more of Young. I also prefer that the C's get in the lottery than in the playoffs. I am not a fan tanking, as in, try to lose. I am a big fan of developing players and increasing the value of assets (while rebuilding). I think Stevens has done a good job increasing the value of the team's players, and I'd like to see that happen with Young over the last dozen games. I think player development is more important than getting in the playoffs.
I'll be in the minority saying this, but getting Rogers/Delk was exciting for a moment but not in the Celtics best long-term interest. Similarly, getting in the playoffs this year may come with some excitement, but may not be in the team's best interest longer term. Let the kid play.
