And that's irrelevant. What's funny to me is that your general tenor here assumes a turnover can only be committed by a pass.
How did I do that?
A turnover can be commited many ways. But if you come up court and shoot right away rather than set up your offense you get a FGA and that counts toawrds this stupid turnover% stat. Meanwhile if Stockton sets up the offense and has the ball for 13 seconds and then passes it to someone who misses a shot, he does not get anything that will lower his "turnover %."
So Thomas has the ball for 5 seconds and shoots, Stockton has the ball for 13 seconds and passes, but turnover% awards Thomas.
All that matters is that Thomas commits 16% more turnovers per minute than Stockton. Turnover% is irellevant here. Both players play the same position and if anything, Stockton handled the ball for more time in a game than Thomas did. The Pistons would many times run plays for Thomas, with Dumars or somebody handling the ball. The Jazz rarely ever ran a play for Stockton. They ran plays for their 2 guard, Hornacek or Malone.
So I take it you won't be using Winshares anymore? And I thought you weren't for using visual context when you have numbers. In any case you're making the assumption that all of those shots by Isiah were bad shots (and of course I'm relying on your no doubt excellent anecdotal opinion) and were always jacked up quick and that somehow this provided a declining value. And just FYI I strongly doubt your assessment of the two players (given how invested you are in your biases) because for all but three years of their contemporaneous timeline Isiah's teams played at a slower pace (often significantly slower) than Stockton's Jazz. And remember pace factor as calculated excludes offensive rebounds as a separate possession so you can go ahead and remove that from an explanation for why. Now this isn't to say Stockton was a chucker (he clearly wasn't) just that your characterization of what Isiah did is almost certainly innaccurate. Both teams had quite measured paces. And Isiah taking 16 shots per game isn't a crazy number. If you want to think of it this way the number of Detroit possessions that ended in a turnover when Isiah touched the ball is fewer than the number when Stockton touched the ball. By a significant amount.
I just showed you how turnover% is fatally flawed. Stockton touches the ball for 15 seconds and passes to a player who misses a shit, Stockton does not get a possession, while Thomas touches the ball for 5 seconds, misses a shot, and he does get a possession.
So each player had zero turnovers but Thomas appears to the formula to have handled the ball while Stockton doesn't.
I happen to think Stockton is a greater and better player for some other reasons you identify but I don't have your strong committment to use figures you don't even really agree with or understand the methodology for to support your point.
I saw both players for their entire careers. In 36 minutes of game time Stockton would have the ball for considerably more time than Thomas would. Not only would he commit fewer turnovers per minute of plaing time, he woud easily commit even fewer turnovers per minutes that he had the ball.
Even at their peaks Stockton was easily better than Thomas, and he played at a high level for much longer too.
