South Forsyth seniors Sam Walker and Isaiah Williams verbally committed to Army football after taking an official visit together this weekend. Walker and Williams are two of the first commitments for new Black Knights coach Jeff Monken, who was hired Dec. 24, 2013, after four seasons as the head coach at Georgia Southern. Walker and Williams’ commitment gives South three players verbally committed to Football Championship Subdivision (formerly Division I) schools, and all are pledged to military academies.
