McKenzie, in his seventh year at William Carey, was named National Women’s Assistant Coach of the Year. His sprints/jumps groups accounted for all 65 of the points that the Crusaders scored in finishing second in the team standings at the 2021 NAIA Outdoor Track & Field Championships. William Carey won three events, the most in the meet, with victories in the 100 meters, 100H and 4×100 relay — nearly setting an NAIA record in the relay. During the regular season, McKenzie’s athletes held three No. 1 rankings on the Descending Order List in addition to 12 top-10 marks.
