Angelique Chengelis (DetNews) spoke with Mattison...here's a few interesting quotes
"The biggest reason is Brady," Mattison told The News on Tuesday night. "I know he's going to win. Michigan is a special place. The longer you're away from it, even when you're in the NFL, it's still Michigan. Every Saturday when we're in our rooms relaxing before the Sunday games, I always watched Michigan. That doesn't leave you."
But he said Baltimore coach John Harbaugh helped make it an easy decision.
"He has so much respect for Brady," Mattison said. "He came into my office and said, 'The job you've done here is unbelievable, but I would understand if you went to Michigan because it's Michigan. I would understand because it's Brady Hoke.'
"Don't worry about me recruiting," Mattison said with a laugh. "Recruiting is all about where you're at. If you really believe in the school you're at … it's easy to sell a place like Michigan."
"He's one of the best recruiters out there — he's a helluva recruiter," Irons said. "I'd put him in anybody's house and he'll sell them on Michigan and will be genuine about it."
