You are basically making it up that he has matured to support your argument. He couldn't even handle playing for Pop the first two years and Pop had to be the bigger person and give in to Aldridge. Neither of us have any idea whether his ego would allow him to fit back in here.
How does playing with Gasol prove anything? Gasol is literally one of the most unselfish bigs of the last 15 years.
Here's the situation. Aldridge left because he thought the grass was greener with the Spurs. Him wanting to come back tells me that he simply wishes he didn't leave after seeing the success the Blazers have had, which is just as much as the Spurs during the last 4 seasons.
