On January 31, 2012 it was announced that Johnson has been hired by Texas Southern to be the associate head coach, co-defensive coordinator, and cornerbacks coach.[3]
Johnson lost the first 12 games of his career—part of an 80-game losing streak over parts of 10 seasons, the longest in NCAA history.[6] However, it was in the fourth game of his second season as head coach when the streak was broken by a 14–12 victory over Langston.[7][8][9] Tensions over the losing streak had grown so high at the school that the entire marching band was suspended by the conference the week before as a result of fighting between marching bands.[10]
