PER GAME statistics is NOT reliable, I said that many times - you would need to look per/48 min. (actual playing time) to see whether a player is effective on the floor for the actual time he played (NOT per game):

Brent Barry's current Tendex is 23.39 which is the 4th of ALL Spurs - Timmy, Manu, and Tony are only before him. He is showing extremely positive spread of (+4.18), which shows you he is still very effective on the floor, helping the Spurs NOT only by scoring, but with all other things. Back to the period you are talking about when his "stat per game" was higher, his spread was only +0.75 above current level, meaning his actual contribution to the team for the actual time he played as a whole didn't go down much (he contributed other ways than scoring!)...he is still shooting .488 from 3-pt range and we look at 3 Point PCT (min 40 atts) here is the ranking:
