I don't think any of us can knock Lue for signing for more money, even $600,000 more (per for 2 I think). It is going to be real hard for him to make any money at all in couple of years. That is exactly why they have a cap and a tax, so that the good team can't aways get who they want.
Eddie House and Tony Allen are both going to have to give careful consideration to whatever offers they get too. The difference of $1M or $2M over 2-3 years for either of these guys is big (and should be). With Tony, I think we have Bird rights of some sort so that we can go higher than the minimum without using up any of the MLE. To go over the minimum with House is going to be alot of the same math as with Lue.
I think Danny is going to only pay the minimum unless he gets someone like Posey who is a top bench player. Tony and Eddie probably don't qualify. If he isn't able to get the value he wants in the off season, I think they start the preseason with pretty much what they have and do what they can during the season to add pieces. I would love to see a couple more top bench players come in here but I understand what is going on I think enough that I am not upset with the Celtics for what they have been doing.
