This is the most sensible deal I can come up with in the scenario ESPN describes. As they suggest, the Celtics give up a 1st rounder in the deal going to Memphis.

I think this is a very fair deal for the Cs, particularly considering it allows them to try to 'win now' but actually gives them Anderson and salary flexibility next year, should they want it. I also think it's interesting for the Griz.
At first glance, I think it looney tunes for TOR. But -- 1) they seem to hate Lowry, 2) they're not going to pay Calderon in the offseason, and 3) Colangalo is desperate to be relevant now in order to keep his job.
That trade makes Toronto very wing heavy and Grizzlies guard heavy. I toyed a bit with your idea and came up with this: http://espn.go.com/nba/tradeMachine?tradeId=auhzlwb.
However, given that Memphis are essentially letting Gay go due to financial reasons, I'm positive that taking back $12m this year is decent enough. However, they whould have to be sold that Green would fit their system and produce adequately (which is doubtful), and that they ship Terry on possibly in the offseason, for further cap relief. And I'm not sold on that, considering his current level of performance.
The incentives for Boston and Toronto are relatively obvious, so I won't go into detail with that.
Don't understand what you mean. Toronto trades a wing and gets a wing. And Lee plays a position where the Griz currently have basically nothing.
More importantly, your deal doesn't follow the report. Participants: Gay, Arthur, Davis, Lowry, Calderon (for salary purposes). The Griz want young players (meaning, rookie contracts), salary relief, and a pick. The Cs come in to put a player in for Lowry and provide the pick. I add Anderson, who is valuable to the Cs but becomes redundant on the Raps, for providing the pick.
