No, Zeigler is benefiting from defenses having to focus on Chandler and Vescovi, which gives Zeigler a lot of room to work. But guess what? Chandler is benefiting from defenses having to focus on Vescovi and Zeigler, which gives Chandler room to work, and Vescovi is benefiting from defenses having to focus on Chander and Zeigler, which gives Vescovi room to work. It's a team sport. They're all talented players, and they're all benefiting from having each other out there to draw attention and keep defenses more honest in how they defend. Take Vescovi's 17 PPG for example. He's certainly doing well this year, and it's due to his improvement, but it's also due to the fact defenses have to do their best to contain Chandler. They cannot leave Chandler, they cannot give Chandler any room. He is too good to ignore. That helps the guys around him find matchups and openings.
I suspect we're going to see a lot of that this year, especially with Tennessee's focus on shooting the three. Depending on who has the hot hand, and who defenses choose to focus on, you're going to have games with Chandler scoring ~20, or Vescovi scoring ~20, or apparently Zeigler scoring ~20. The backcourt scoring's gonna bounce around like a hot potato all season. A beautiful, lethal, SEC-championship caliber hot potato.
