They're not the same. Events for and against... possession.
But if one was poor in zone exits, would you expect them to be a positive possession players? Virtually his entire career?
They're not the same but it would be silly to believe that there isn't a relationship reflected in those numbers.
I don’t think Sverson struggled with zone exits but I’m skeptical what amounts to a team stat is necessariky a correlation with a micro stat like zone exits which as I understand it are tracked individually. I guess you don’t need corsi if you can just look at the individual actual stat?
