He was first seen in Close to Me helping K.C. Guthrie with his basketball skills. After K.C. wasn't playing well in the basketball game, he pulls him out because he "sucks" in the basketball game, which infuriated K.C.
In Heart Like Mine (1) and Heart Like Mine (2), Coach Carson helps K.C. with his Clare problems. He encourages him to break up with her, and K.C. decides to take his advice, as he liked Jenna more than Clare. Coach Carson takes him under his wing, almost like a father figure that he has never had, since both of his parents are in jail. At the Athletes Banquet, Carson awards K.C. with the Most Improved Player title. He then gives him the his hotel room key for him and Jenna, K.C.'s new girlfriend. After he walks in on K.C. and Jenna making out in his room, Jenna goes back to the Banquet, and K.C. decides to stay in the room with him. While they were in the room together, Coach Carson offers K.C. beer, and they end up watching porn together, as K.C. admits he doesn't know what do while having sex. Coach Carson tells him to watch it for visual aid, so he nervously continues to watch it.
The next day, K.C. returns to the hotel room, and it seems that Carson hired a prostitute to "relax" K.C. before the game. K.C. freaks out and quickly leaves the hotel room. Coach Carson also shows K.C. the gun that he keeps in his car, which K.C. finds strange. The next day at Provincial Finals, K.C. decides to get the gun out of Coach Carson's car and ends up showing it to Ms. Hatzilakos and Mr. Simpson. K.C. tells them everything, and Coach Carson is later arrested while coaching the game. While he is escorted out, he glares at K.C.
