Leo has won 29 of its last 30 ACAC contests dating back to 2008, with many coming in dominating fashion.
But that does not mean that the Lions have not had their share of tests.
Consider last season when Leo entered a showdown against Heritage with a state ranking and an undefeated record.
It escaped with a three-point overtime victory.
That was followed by a narrow win over Woodlan and a loss to Garrett.
Now, the once again unblemished Class 4A No. 10 Lions (5-0) face the same three teams over the next three Fridays, beginning with Heritage (4-1) this week.
“Our guys know this is the toughest part of our schedule,” Leo coach Jared Sauder said. “These three games come at a difficult time. It is the middle part of the season, guys start getting banged up … and it is three really good football teams.
“We have a tough challenge for us.”
At the top of the list of challenges the Patriots present is quarterback Branson Dossen. The junior leads the area in passing yards with 1,403. He has completed 71 of 141 passes for 13 touchdowns.
He is a primary reason why Heritage averages nearly 30 points per contest.
“(Dossen) presents some problems for us,” Sauder said. “He throws a great ball and he gets rid of it quickly. His receivers are quite young, too, and they have big-play potential on almost every play.
“It will be a challenge for our defense.”
So far this season, Leo has been up to every challenge thrown its way. It is surrendering just five points per game, with the highest scoring by an opponent being 12 by South Adams last Friday.
The Lions' success on defense so far this season has been nothing exotic or difficult to master, but simple fundamentals.
“The big thing for us so far has just been really good assignment defense,” Sauder said. “Everyone is playing their assignment. We run well, we tackle well and we are getting guys to the ball.”
After the first five weeks of the season, the Lions sport a plus-14 turnover margin.
“Our guys are just executing the defense, playing fast and getting to their spots,” Sauder said. “Our offense has had some pretty good opportunities to score because of our defense.”
Leo will need more of the same against a Heritage team that has knocked off three consecutive league opponents.
Sauder is not about to let his team forget what happened last season with the stretch beginning with Heritage.
“Really the three games last year against Heritage, Woodlan and Garrett, we didn't play well,” Sauder said. “We made a lot of mistakes, and that is something we brought up. But this is a different team and a different season. We are really happy with our senior leadership, and, from what we see, our guys are pretty focused and set on what their goals are and what they want to accomplish.”
Heritage will aim to upset those goals Friday night.
