Preffered Walk On

I was just wondering if being a preferred walk on counts for any attention? His name is Erik Gunderson, from Milan and he is going to be a preferred walk on at UM. He is a 6' 9" 325 pound O-lineman. He wasn't recruited because he didn't begin to play until his junior year in high school and coaches didn't have enough info/ already gave away scholarships. He had interest from western, central, eastern, ball state, northern illinois, robert morris and MSU. He mowed people over in HS, but college is slightly more competitive. I thought I'd mention.
