I dont see the purpose of waiveing Lester Hudson

What did we gain in doing that. I thought we were just making a spot to fill in with a better player.But now that we traded 3 players for 2 we have to spots open. Now Lester Hudson is a great player for the grizzlies. It seems like a waist

Lester since hes been with mephis is averaging a little over 4 pionts in less then 8 mins that would have been nice for the celtics.
