On Thursday, during a press conference to discuss the start of bowl practice, Will Muschamp officially announced the signings.
"Yesterday was the junior college signing day and Keisean Nixon from Arizona Western, a defensive back that we're really excited about him being a part of our program, and Kaleb Chalmers from Northwest Mississippi signed as well," Muschamp said. "Those two guys will make our football team better moving forward."
Both prospects will arrive in Columbia in time for the spring semester in order to go through spring practice with the football team. Muschamp says there's a chance that they could practice with the team for some of the bowl practices in Columbia.
Both signees are expected to contribute right away for the Gamecocks next season.
"Athletically, from a speed standpoint, but run extremely well," Muschamp said. "Both have really good ball skills down the field as far as judging and playing the ball. Both can finish plays down the field. So I just think from a speed standpoint [and] both have shown to be solid tacklers on tape. The physicality of the game, I think in all areas they make us better."
Chalmers is a former Greenwood standout who signed with Clemson out of high school but went to Northwest Mississippi after being dismissed by Dabo Swinney. Chalmers has three to play three.
Nixon is originally from Salesian High in Compton, Calif. He has three to play two.
