I haven't weighed in on any of this because I think this level of debate about a former guy who won't help us win any games this year is silly. I don't have a horse in this race- I liked IT, I like DC, and I just want to win games.
But the bold comment above, while true in a technical sense, is not true in reality. Anyone arguing that the decision was IT vs. a Trade Exception is creating a straw man to troll people. We were never going to have IT and DC. IT would not have resigned here to be the 6th man. He wanted to start. He still wants to start in Phoenix. He will always play to usurp the starter. He never bought into being a bench guy here (and often for good reason because he was better than the starter), but he always played to prove he should be the starter, not to be a bench guy. I respect him for that, but I don't think you were going to resign him to be DC's backup.
Nor were you going to sign DC to back up IT. DC has made it clear that one of the main reasons he signed with us is because we were giving him the chance to be the starter. You don't leave LAC, backing up Chris Paul and playing for championships to come to Sacramento, back up IT, and try to win 35 games. It just doesn't happen.
So while technically you could have had the money to make it work to have both, it never would have worked in reality. The front office had to make a choice DC or IT. Once they made that choice, they got what they could for IT (which was the trade exception). Maybe they could have gotten more, maybe they should have played their cards better, etc..., but they got the trade exception because they chose DC over IT, and knew they couldn't have both on the team for chemistry purposes.
So the question IS ACTUALLY whether you would rather have IT or DC. We did the IT "starting point guard" thing and it didn't work out great. I don't think you win more than 40 games with IT-Cousins-Gay. Maybe you win even less with DC, but I don't want to be capped out at 40 games with IT as my point guard. I would rather roll the dice with a worse scorer and better floor general and see what happens. It is too bad it happened the way it did, because I think IT is a perfect sixth man, but don't fool yourself into thinking the front office's decision was not IT or DC. It clearly was.
