He could probably add a 3rd day of hard training near the end of his mesocycles. However, that is why I think you need a coach there to watch, I think feedback is the most crucial element to improvement, variation, and changing the programs design when it is needed. My seasonal plan has 2-3 hard and medium hard days in the competitive season mainly because of 2 competitions per week, however when I get to that point in my season I may deviate from my plan.
Also, too much focus on weights shifts your focus away from speed and power into strength and size. 2 Days per week in the weight room should be enough.
