MCKINNEY, Texas — Basketball practices at McKinney Christian Academy are, by design, intense. “Intense. Physical. Demanding. High energy,” head coach Fonzo Martinez said. They have to be. The Mustangs entered the season as the preseason No. 1 team, carrying both expectations and unfinished business. “We were preseason number one. I think there was a little bit of pressure,” Martinez said. A year ago, MCA came up just short, losing in the Final Four. The loss lingered.
