A steady, physical Jacksonville State corner who already earned a role
In the 2025 season, RJ Rainer appeared in 11 games for Jacksonville State, finishing with 13 tackles and 1 pass breakup, and he even drew a start in the CUSA Championship game—nice proof the staff trusted him when it mattered most[7]. At 6-foot and around 180 pounds, he brings a compact, willing-tackling profile more than flashy ball production, and his three-star recruiting background suggests a solid developmental upside rather than a finished product[7]. The appeal here is toughness, reliability, and early-game experience; the question is less “can he play?” and more “how much higher can the ceiling climb?”[7]
