In the last CBA update (where it was revised to avoid a lockout) CP3 was the head of the players union. One of the big things to come out of this most recent update was the ability for players of CP3 age/time in the league being able to get bigger pay days at their age. Also, with the benefit of hindsight, this CP3 type deal should have been so obvious. We knew 2 things: 1) CP leaving LAC was a legit possiblity & 2) He abused his power as a players union president basically to get that new contract in his favor
So knowing those two things, him leaving LAC would only happen via trade since we know he was damn well not going to give up that money. Not only that, TX should have been obvious since not only is getting the same deal he could get in LAC a big deal, but getting it in TX MEANS EVEN MORE MONEY FOR THAT SAME DEAL.
