This is one reason I hope Ainge doesn't trade Green or any of our other vets who are making contributions this year, unless he gets a ridiculous offer, which isn't likely. We have such a glut of picks we already can't possibly keep all of the players taken with them, so another pick even if it's at the end of the first round isn't going to move the needle any in terms of what we can do. I was all for selling off and bottoming out last year, but part of the reason to do that is to collect assets and clear cap space. Ainge has done a good job of that already.
This team has shown itself to be moderately competitive this year (6th best diff in the East!) and it would be a shame not to give them the best chance to keep getting better and compete for a playoff spot. Even if Green opts out and signs elsewhere, the addition of yet another mediocre pick wouldn't mean anything, while the loss to this team's competitiveness and the experience they could get playing meaningful games and winning basketball, not to mention what it would mean for the fans and organization to watch a playoff team in only the second year of the rebuild, would. (And for those who claim the 7 - 8 seeds are automatically NBA purgatory, not all 7 - 8 seeds are created equally. I.e. if you do it with young guys and a lot of future assets, you're moving up, not standing still, like the Nets or Heat.)
