"He took half the reps in game one against Parkway," said his father, Sean Patterson. "Then he took all the reps the next week against St. Thomas More.
"Those were two rough games. The most recent game was a 28-23 loss to West Monroe. In the game where we beat (4A) LaGrange, Shea had 200 yards passing with three touchdowns in the first half."
Over the past four weeks, Shea has thrown for 1,000 yards with 10 touchdowns and no interceptions. He had 245 yards through the air versus West Monroe.
"He's still committed to Arizona," the elder Patterson proclaimed. "He's that type of kid who is really concentrating on winning the state championship. He calls the Arizona coaches and has a great relationship with them.
"Those are great guys who've built a relationship over a year and a half. He visited LSU for the Auburn game, which was pretty exciting. Coach (Les) Miles and Coach (Cam) Cameron really love him and said he's at the top of their 2016 list."
"We got to kill two birds with one stone that weekend because his brother's been up there in that area," dad said. "There were 115,000 people at that game. The offensive coordinator, as well as Fred Jackson, who recruits this area, like Shea a lot.
Once again, Patterson emphasized that his son remains committed to Arizona.
"He's pretty focused on Arizona and trying to get to the state championship," dad said. "The main thing in his recruiting process that's changed is his older brother Sean, who played quarterback at Duquesne, is working with him.
"Sean wants to become a college coach and every day they go over film. We were supposed to go to Arizona's game against UCLA, but the coaches know we just moved from Texas to Louisiana, plus we had a death in the family and I have two daughters, so we'll get out there to Arizona by spring at the latest."
Calvary Baptist may be 1-4 but the Cavaliers are expected to have the inside track for a berth in the title game.
On paper, Catholic-New Iberia, with 2015 QB Jason Pellerin, is Calvary's main competition for the state championship.
