Danny Ainge's plan is to not trade anyone for the sake of trading him so that by the time the Celtics are contenders, he's not relying on Ryan Hollins-level players to fill out the bench.
Teams that are looking for reinforcements for the playoffs are not the sort of team to be discarding the star that Ainge wants.
I think gambling for a star to become available , especially one that fits our system, is just as risky as the draft lottery.
Your right about the Ryan Hollins, I would have said Scal, but teams that have young star talent know that they need to get quality bench guys for the future.
Look at the Pelicans. I was against them trading/signing players to come in and help AD. That is crazy but they should have played the draft for another year or maybe 2(which currently they are but not by choice). I can understand why they did it but I think they would have been much better off keeping their picks and Nerlens Noel.
They wanted to show AD that they supported him so he would feel like he could win there/be supported. Instead they jumped the gun and let their insecurities about AD's happiness with the team dictate their moves.....I see a faint resemblance to how we as a fan base and as a team treat CBS.
