People keep posting about LA putting off the surgery as proof that he is committed to the Blazers in the long term.
Maybe. Maybe not.
First, it might have been more for the sake of his teammates than the Portland Trail Blazers. Those aren't the same things.
At the time LA decided to play through the injury, the Blazers were a very strong contender, too. Wes was healthy, RoLo was coming back, there was no reason to believe Lillard would get into his current rut, and the team was poised to add something at the trade deadline, which it did. So he was chasing a title at the time, and, simultaneously, he or his agent could have thought he was proving to potential suitors that he was willing to sacrifice and play through injury.
So let's not delude ourselves into thinking there was absolutely nothing for LA himself to gain by putting off the surgery. Although it wasn't without some risk, there was a lot individually to be gained from it.
