I agree he has the tools. And on the Celtics, he would be asked (to put it nicely) by the team leaders.
It is still a worry when adding a player.
And this is why standing pat, and just adding a couple veteran role players is the safest route to another year of contention, and why I think it is what they will end up doing.
No matter who they add, you have no idea how they are going to fit into the team.
It's tough, because this team absolutely had something special two years ago, and even if they kept the same team completely intact, it would have been almost impossible to repeat the magic they had. Everything came together perfectly, and that rarely happens.
So the tough balancing act Danny now has is to balance what they had with what they could have in the future. When you have a team that good, its a huge risk to completely tear it apart, because you may never get the magic back, but at the same time, if you stand pat too long, things will get stale, and it will just be a disapointment.
I just don't envy Danny at all right now. He is in an incredibly difficult spot. He either risks the team slowly fading back into obscurity, by not trying to do something bold to keep them at the top, but if he does do something too bold, he could disrupt the delicate balance they had, and they could fall into obscurity anyways. So basically, he is relying on luck again. And we just have to hope it hasn't run out.
