It all really depends upon the athlete, their strength levels, their sport, and their fighting style. If the guy is weak for his sport/weightclass, I'd have an early focus on GPP with emphasis on compound movements with progressive overload (squats, overhead squats, press, pull ups, deadlift, etc). As he progressed I'd move more toward triple extension/explosive movements (box jumps, clean variation, snatch, hill sprints) as well as continue to address weaknesses. Then I'd focus more on sports specific movements and adapting that strength and power to motor patterns for the sport. For instance for a wrestler I'd focus on exploding into double leg, suplex, exploding from bottom position.
