Wisconsin is losing four scholarship linebackers after 2014 and with the Badgers looking for big, fast backers for its 3-4 scheme, Cook impressed Busch enough to get a scholarship shortly after the two met.
"I just feel blessed that I have this opportunity," Cook told BadgerNation. "I know a bunch of athletes who wish they had this offer."
Trezy is expected to compete right away at Wisconsin this fall at the safety position. Trezy gave his verbal commitment during an in-home visit with Gary Andersen and Busch in December and has spoken highly of his new university.
"I have talked with (Serge) about how Wisconsin has a great program they are running," said Cook. "I know he wasn't sad about signing there when it came to decision making time, and I can say I would have the same feeling. It would be a great opportunity to play with Serge. I surely wouldn't waste that type of opportunity."
Cook sits with other offers from Arizona, California, Cincinnati and Memphis and is hearing from Arizona State and Utah. However his Wisconsin offer has moved the Badgers up to the top of his leader board.
"Wisconsin is my leader," said Cook. "I will for sure plan on taking an official there. I'm super excited to take a visit and be around the wonderful atmosphere of the Wisconsin Badgers. I know I would love to see myself playing for them."
Cook is being recruited as an athlete after playing linebacker, defensive end and running back last season. Cincinnati and Wisconsin are recruiting him as a linebacker, while Arizona, California and Memphis are recruiting him at either side of the ball.
