Not sure why people are citing the Clippers' series when it was evident that Splitter could barely move, tbh

..his health was probably the biggest reason the Spurs lost the series IMO..
And ya, while the OP is correct, a 20-game sample size is pretty small, especially since it occurred early in the season(early season results generally don't determine the final outcomes, excluding a few teams per season)..while Aldridge is an above average defender when engaged, the biggest difference is going to be mental..Splitter's job and focus was defense, while Aldridge has been the #1 option on a team for the majority of his career, it will take a little time to adjust to tweak his role to slightly less offensive and a little more defensive..
