King, who is 6-5 and 270 pounds, received an offer from Northwestern earlier in the week. He also had offers from Toledo and Western Michigan.
“Blake King is a great character kid that is truly driven to get better in everything he does in the classroom, weight room and on the football field,” said Bert Kooi, who retired as Minooka’s coach after last season. “The sky is the limit with this kid. I guarantee you we will hear a lot more about Blake King.”
Northwestern now has two Class of 2013 commitments. King joins Maine South quarterback Matt Alviti in the recruiting class.
