There is an article on The Athletic site that talks about TBP's recruitment. Apparently he was highly recommended by his HS coach, who has some history with Marcus Freeman and has picked up on some diamonds in the rough before, including LB Ivan Pace, Jr., who was lightly recruited out of HS but became a unanimous AA and was named AAC Defensive POY. So MF trusts the coach's judgment. TBP played rover in HS, but they apparently see him projecting as a safety, with great potential upside once he gets some coaching:
“He’s got tremendous range when it comes to the ball in the air as a middle field safety,” Huls said. “But if you’re playing Cover Four, he can run the alley and hit. He’s a big kid. When he gets to college and has got position coaches with him nonstop, is watching film, really gets specialization that you don’t get at the high school level, who knows what his potential could be.”
