I said this several times during the offseason: even if Aldridge doesn't end up being as good as people hope, there will be a clear improvement just from the fact that he can give us 30+ mpg for 70+ games a season, whereas Tiago is giving you 20 mpg for 50 games. People were worried about the defense falling off due to replacing Splitter with Aldridge, but it comes down to "would you rather have a good defender for 2500 minutes a season or a great defender for 1200 minutes a season?". It's even more lopsided now considering Aldridge has shown he can be not just a good defender, but a great one.
Splitter, when healthy, is a great player and I'd love to have him back on the team as a bench guy. But relying on him as a starter and the only true big outside of a 40 year-old Duncan is an absolute recipe for disaster. As always, PATFO showed great foresight and made the right move.
