Pratt, in one fewer game, is 26-of-44 for 509 yards, 5 TDs and 2 INTs.
"The most difficult thing to defend in high school football is a quarterback as a runner and a scrambling-type passer," Mays said, mostly in reference to Pratt but in an explanation that also described his own quarterback.
"That's a problem in itself, just trying to figure out how to stop someone who can do that.
"How do you do it? Pure effort. It's the kids that have to be in the right spots at the right time, not giving up containment, forcing the quarterback to make quicker throws and little things like that.
"If you get out of position, Pratt will exploit it."
As soon as either team devotes itself to stopping the other's passing game, however, Capital's Kashuan Haley and SC's A.D. Cunningham could quickly rise to the forefront.
The junior running backs lead their respective teams with 402 and 361 rushing yards, respectively. Haley has carried just 31 times, and averages 13 yards per carry.
The game serves as the second of three straight home games for South Charleston, but opens a three-week stretch for Capital in which it must play the Black Eagles, No. 3 Huntington (4-0) and No. 6 Cabell Midland (3-1) all on the road.
"It's a big rivalry game," Capital senior defensive end James Walton said this week. "But right after that we've got Huntington and Cabell Midland, which are also big games. It'd be easy to look ahead to those but since this is a big game, because it's South Charleston, we're minding our Ps and Qs this week.
"It's strictly business."
Kickoff is set for 7:30 p.m.
