It clearly is unlikely, but we have discussed considerably less likely things on this forum before.
However, in the unlikely event that Aldridge talked with the C's and informed them he would sign here if we gave Matthews the ~16MM max deal he wants then I would do it in a heart beat. I don't really see a better outcome to this summer than adding two players who immediately become our two best players, without giving up a single asset besides cap space.
Argumentum ad passiones and red herring. I rest my case.
Ok I looked that up so I could disagree lol.
I'm not sure how I am appealing to emotion and what the red herring was. We were discussing if it would make sense to do such a deal, not if it was likely (since I already stated it was unlikely and that we discuss unlikely things all the time). I didn't use emotion or try to mislead, I simply stated that signing LMA and Matthews would be a great move.
Argumentum ad antiquitatem!
I'm nitpicking

Appeal to emotion: where are your facts, Sir? All I see here is excitement and dedication to your team, but this can easily lead to wishful thinking.
Red herring: 'adding two players who immediately become our best players' introduces a new element to the conversation that is not relevant to whether these are
the two best players to sign or more generally speaking this would be our best possible move for the summer.
But again we are arguing backwards, we are going from what would be best for the team to what is likely to happen. Even if this were the best of all possible moves for this summer, this makes it only marginally more likely to happen since it can influence decision making only on the Celtics side. Aldridge et al could care less about what is best for us.
Personally, I think the conversation is more fruitful if we discuss better substantiated rumours (eg from journalists who are likely to have inside information) and the options of the player. It does look like Aldridge is considering leaving Portland what other likely destinations are out there?
There are a lot of articles on Aldridge moving to Dallas and SAS. Then some journalists mention LAL and Knicks. The C's could be a dark horse in this race and it is too early to dismiss
entirely the possibility of him coming to Boston, but for the time being we are just an outsider and nothing more than that.
