It is not waiting to make a pick.
It is about waiting for a good move to become available.
(and here is the hard part for many)
That move may not come until the offseason!
And that is OK. As long as the team is moving forward, which it is. As long as their is growth in the players, which there is.
Unless a miracle happens and multiple stars become available before the deadline, the Celtics trade for all of them and they fall perfectly in place with the remaining players; the Celtics are not winning a title this year.
They will either make the playoffs or just miss the playoffs. The same position they are currently in.
There is no quick fix.
There is no reason to take a step back.
It is the time to allow the player that they have grow and wait for (or create) the right trade.
