The Zeller brothers each took a turn being Indiana’s Mr. Basketball. They reached a combined height of just under 21 feet, and each attended a powerhouse athletic university. But like most of the groups of three or more brothers to make it to professional sports, one will probably stand above the rest.

The Charlotte Bobcats, who selected Cody, the youngest of the three Zellers, with the No. 4 pick in Thursday’s draft, will be hoping they have the right brother. By all indications, they just might.

Zeller, a 7-footer who weighs 230 pounds, is roughly the size of Bill Walton, a Hall of Fame center. But at the N.B.A. draft combine, he performed more like a guard, with a vertical leap of 34.5 inches and top-10 finishes in all of the agility tests.

His performance may have wowed scouts, but it did not seem to come as a shock to his oldest brother, Luke.
