Castleman got playing time as a true freshman last season and began fall camp third on the depth chart. But by the opener, Castleman had risen to one of the starting spots. He had his best game against Arizona (nine tackles, 0.5 sacks, two pass break-ups) and has helped solidify OSU's front seven, and entire defense, throughout the season.
“(Castleman and Barnett) terrorize the offensive line,” Bassett said. “And not only do they get in their gap, but they rip off and they make plays. They pressure the quarterback, they make tackles.
“With James' strength, size, athletic ability and speed, he truly is a special player.”
Since arriving in Stillwater, Castleman has beefed up to nearly 300 pounds, which Bassett said now makes him a “bully” on the basketball court.
But Saturday on the gridiron, Castleman will line up against the team he was committed to for several months.
Has that crossed his mind? Not really.
“I never think about how I could be on the other side, on that team,” Castleman said. “I'm definitely here for a reason.”
