What this means is that 44% of our opponents' possessions while Tyler was on the floor ended with a score and 56% of their possessions ended in a stop. What I'm looking for in the table are players who has a number far different from the team number, and Tyler is the only player with a significantly higher percentage than the team.
Of course, one could argue that this stat was invented for a player like Tyler, who doesn't stay in front of his man so well but is a great help defender. Either way, at least in the sample of games Tommy has charted, our defense performs significantly better with Tyler on the floor than it does when he's not on the floor, and he's the only current Duke player about whom we can say that.
Is it a problem that our team only stops the opponents 52.4% of the time? Probably. That's why we're all talking about defense. If the entire team's stop percentage was 55.8% (Tyler's stop percentage) instead of 52.4%, that would mean we'd prevent an additional 2.4 scores per game, and we'd probably be a top 20 defense on Pomeroy right now.
