A native of Pittsburgh, Pennsylvania, Posey attended college at Morgan State and Slippery Rock, playing on defense for both of their football teams. After earning a bachelor's degree in political science from Slippery Rock, Posey became an assistant coach at Clairton High School. He earned his first college coaching job in 1995, as Slippery Rock's linebackers coach.[1] In the following years he would serve as defensive line coach for East Stroudsburg, Edinboro, Johnson C. Smith, North Carolina Central, and Delaware State before being promoted to Delaware State defensive coordinator in 2003.[1] In late 2003, Hornet coach Ben Blacknall was fired after posting a 0–6 record.[2][3] Posey was promoted to interim head coach[4][5] and served in the final five games, compiling a 1–4 mark. He did not return to Delaware State the following year.
