Of the four schools Anderson is considering -- Oklahoma, Ohio State, Miami (Fla.) and USC -- Carroll is the last coach to make an in-home visit. He arrived with two USC assistants.
"It was good to have a chance to sit down with Coach Carroll," Anderson said. "They said they took a private plane to come talk with me. I did not commit.
"I have narrowed it down to four schools -- Oklahoma, Ohio State, Miami and USC. All of the head coaches have been in now. Coach Tressel was in last week and the visit went pretty good.
"I plan on announcing on signing day (Feb. 4)."
