I just looked up there career defensive stats per game, and Pippen's stats are better. It's hard to judge defense w/o watching both players. Stats don't tell the entire story. The best stat doesn't show up, and that is keeping your guy from even touching the ball.
From the things that can be compared, the only concrete thing we have to go on, the numbers are yours, so I'll concede.
Wow, how about that, an Internet Poster tipping their hat to someone in a discussion!!!
Defensive Win Shares actually show Sidney had a few absolutely amazing years, however over the course of a 17-year career Pippen was consistently great. Sidney's 1981-1985 is probably the best run of DWS in history.
