The four-star recruit says these programs set themselves apart from the 42 others because of their coaching staffs.
"They communicate with me," Mathis explained. "They're always talking to me about life or about my classes, not just football and stuff so that's the reason why I picked them."
Mathis is not shy when it comes to talking about his dream of making it to the NFL, but if pro football isn't in the cards, Mathis says these schools provide a strong fallback.
"(I want) a good business program," said Mathis when asked what other qualities he's looking for in a school. "Just somewhere I want to stay for four years and just a good coach that will get me to the NFL."
Mathis also laid to rest any rumors that have been circulating about a rift between himself and the staff at USC.
"They stopped communicating with me," Mathis said.
When asked if he knew the reason, Mathis said he was unsure. However, he insists the Trojans are right back in the hunt for his talent.
"It dropped off a little bit, but now they're back, so they're in my top ten."
Mathis has taken unofficial visits to Michigan, Nebraska, and Washington.
He will revisit the Huskies in the Pacific Northwest on Thursday.
"I'm going to Washington this Thursday," Mathis said. "My trainer is going to be coaching at a Nike camp up there, so we're going up there to just talk with the coaches and stuff."
Mathis intends to cut his list of ten to five by the middle of his senior season.
He plans to announce his college commitment at the Army All-American game.
