"Coach 'B' (Keith Bhonapha) and I talk a lot, at least once a week," Mattison told Dawgman.com. "He came down and saw me back in January and he offered me and then he brought the head coach (Chris Petersen) with him and I met him too.
"They have done a good job of recruiting me and I really am interested in Washington.
"I'm going to take a trip up there in April for their Junior Day and I think that will be a good chance for me to see what they have to offer and meet with all of the coaches and see the campus and the facilities."
In addition to his offer from the Huskies, Mattison also has full rides from Colorado, San Jose State and he's been hearing from the likes of Yale, USC, Arizona State, Washington State, UNLV and Missouri as well.
"Honestly, I've just been talking to a few coaches and stuff, there hasn't been a ton of interest so far, but a little bit here and there," Mattison noted. "I had a good SPARQ performance a few weeks ago (he scored a 112.74 at the Opening event in Los Angeles) and that got me a couple of coaches who said they want to see me this spring and they will be by to check out what I can do."
As a junior this past season, Mattison posted over 2,017 yards and 26 touchdowns.
"I'd say I am a balanced back. I can do whatever you need me to do," Mattison said. "I have good speed for my build (4.5) and I think that surprises some people.
"I played both ways as a sophomore, but when I was a junior, the first game, I had over 300 yards and my coaches said I needed to stay healthy, so they only wanted me on offense."
As far as when he plans to make a decision, Mattison said he's unsure of timeline, but hopes to take at least a few of his official visits this fall before he begins to think about committing.
"I'd like to take at least a couple of them to see different schools and hear what the coaches have to say," Mattison said. "I'll probably wait until after my season, but it might be mid-season. I'm not really sure when it will be. I have to feel right about things and feel comfortable in my decision and then I will commit, but as far as when that will be, I'm really not sure just yet."
Mattison said he hopes to make some spring practices to schools like USC and Arizona State and he's currently working up a plan for hitting some camps this summer.
We will have more on Mattison after his visit to Seattle next month.
