Yeah but it isn't just playing that would qualify him. You win a basketball game by scoring more points than the other team. Peja has been either the highest scoring player or the second highest scoring player on the team every year that he's been a starter and he's been with the team the longest out of Chris, Vlade, Bibby, Doug, and Bobby. I don't deny that Bibby's impact on the team goes beyond the boxscores, or at least beyond PPG, and his bigget contributions have been in the playoffs, but you're just dismissing 20 ppg season after season as if it's nothing. I don't think either one of them has earned a retirement yet, but Peja is closer than Bibby as of right now.
And the reason I look at numbers is that they're more reliable than the subjectivity of a fan's memory. No, they aren't everything, but they don't lie either.
