"I think I really improved a lot," O'Brien said. "I really improved in the run defense. I think I finished with over 100 tackles and I overcame double and triple teams to make tackles. It is frustrating when you are getting double and triple teamed."
He's watched Tennessee struggle on the field this Fall, but he's remained firm to his commitment. Other prospects have heard from programs, but has O'Brien been fielding those same phone calls?
"Iowa actually called me today," O'Brien said. "I'm not going to look around. I talked to Dalton about the situation and I told him that Tennessee is where I want to be. I'm done."
He's stayed in constant contact with the Tennessee staff and he'll actually see members of the Vol coaching staff next week.
"I talked to coach Sirmon yesterday," O'Brien said. "He and coach Dooley are coming to visit me next Monday when I get back. He just wanted to touch base with me and wanted to make sure that no one was saying untrue stuff about Tennessee. He wants me to be a leader of the recruiting class and talk to the other guys and make sure everyone is staying focused."
