But he has seen the footage.
With the third- and fourth-string quarterbacks not available because of injuries of their own, McGivern was called on, even though he had a sprained left ankle and was not able to run on it the day before.
"I was told I would only be in there if there was an emergency," McGivern said. "Then the first play, here's the emergency."
Despite his noticeable limp, McGivern responded well, going 4-for-6 for 118 yards and a pair of touchdown passes to running back JaRon Hill in a 21-0 victory.
The first touchdown pass was a 67-yard screen to Hill in the second quarter to put the team ahead 14-0. That's when McGivern said he felt like Gibson.
"When JaRon scored his first touchdown, I distinctly remember hobbling down the field, and offensive linemen and defensive linemen were zooming past me," McGivern said. "But it was a nice moment."
Once the Crusaders, who host Loyola on Friday in a Catholic League Blue game, took a three-touchdown lead, coach Steve Nye used running back Charlie Finn as a quarterback the rest of the way.
Nye said Parrilli is out for five weeks, so McGivern will get the nod as the new starting quarterback.
"He came in, hobbled around and did a great job," Nye said. "He's a versatile player. To be able to do that says a lot about him."
Loyola at Brother Rice
When: 7:30 p.m. Friday.
Where: 10001 S. Pulaski Rd., Chicago.
Last meeting: 2009, Loyola won 24-7.
Records: Loyola 4-1, 1-1 Catholic League Blue. Brother Rice 4-1, 1-1.
Players to watch: Loyola -- Malcolm Weaver, Jr., QB, 5-11, 165 (63-for-119, 973 yards, 14 TDs; 3 rushing TDs); E.J. Webb, Sr, WR, 6-5, 200 (22 catches, 419 yards, 5 TDs). Brother Rice -- JaRon Hill, Sr., FB, 5-7, 191 (55 yards rushing, 2 TD receptions against Gordon Tech); Billy McGivern, Sr., WR/QB, 6-0, 185 (4-for-6, 118 yards, 2 TDs against Gordon Tech).
X and O factor: Stopping Weaver and his tall receivers -- Webb and 6-2 Charlie Dowdle -- will be the priority for the Crusaders defense. The Ramblers will have to watch out for the screen passes from McGivern to Hill, which produced two long TDs against Gordon Tech.
FYI: This is the fourth road game in five weeks for the Ramblers and fifth home game in six weeks for the Crusaders.
He said it: "E.J. (Webb) has a lot more speed than people think. He can catch a little slant and turn it into a big gain." -- Loyola coach John Holecek.
