I disagree with that. How many jazz teams got bumped in the first round by underdogs? Jazz chocked in the playoffs for years until making the finals. Then they choked in the finals. Stockton had a couple big shots but those are all you remember, not the misses and the disappearing in the playoffs at the end of games.
Also, all we can compare is these guys at this point in their career. Stockton was no where near Mitchell his first couple years in the NBA and Stockton was older as a rookie.
Stockton was great but be was not the greatest point guard of all time. Saying pure PG is just an arbitrary category. Also again Stockton had a very long career where he played at a high level but his peak was not as elite as others. There was a reason Stockton wasn't top 10 in MVP voting, because he wasn't top 10 player in the league each year.
I'm old enough to have watched plenty of Stockton. But I know that this is a jazz board and some of our older people here idolize Stockton and Malone and put them higher up then they are.
