Leading the way for the Lions was junior running back Antonio Oliver, who rushed for 189 yards on 27 carriers and a touchdown. Tyree Johnson and Myron Robinson combined to rush for 96 yards and a touchdown.
McKinney’s air attack, which was effective in their opener against Mansfield Legacy, was practically non-existent, as Bryan Sutter went 7-10 for 53 yards and a touchdown. Johnson was a perfect 4-4 for 52 yards and a score.
McKinney dominated the time of possession Thursday night, controlling the ball for around 13 minutes more than Heritage.
The Lions carried a slim 7-0 lead into halftime Thursday night, but scored 21 points in the second half to seal the 28-14 win.
McKinney currently sits alone in third in the 5A Region II District 10 standings, a game behind Plano, Allen and Plano East – all of whom are undefeated.
The Lions will be back in action Friday when they take on Nimitz at Ron Poe Stadium. Kickoff is slated for 7:30 p.m.
