Now, an ACC program has reportedly entered the mix.Duke is pursuing Johnson, according to 247Sports’ Chris Hummer. Johnson would have to sit out next season in Durham and would become eligible in 2019.He has three seasons of eligibility remaining.A source close to the situation tells 247Sports the Tigers have given Johnson a full release, which means he’s allowed to join other ACC schools, if he so he chooses.With that under consideration, 247Sports has learned Duke has entered the picture for Johnson.The Blue Devils are now among the known schools in the running along Northwestern and Purdue, the schools 247Sports reported as early favorites last week when the news was announced.As a true freshman, Johnson threw for 234 yards and two touchdowns, completing 21-of-27 attempts.
