As the Bishop McNamara players were removing their helmets as the clock expired on a 34-9 win over Georgetown Prep on Friday, first-year Coach Keith Goganious rounded them up, told them to strap their helmets back on, and get to the sideline.

He preached to his players about discipline as they ran five exhausting up-and-back sprints, after which Goganious signaled helmets could come off, told his players to take a knee, and discussed the message he’d just sent.

“I had to get a point across: Too many penalties,” said Goganious, who played five years in the NFL. “Penalties can kill us and we’re getting them for no reason. We have got to do better than that.”

The Mustangs (2-0) committed 15 penalties for the second-straight week, for a staggering 115 yards. But for Goganious’s young team, those lumps look like a small price to pay given the talent shown against the Little Hoyas.

Georgetown Prep (1-1) had no answer for Mustangs sophomore quarterback Ramar Williams, who threw for three touchdowns and ran for another in the Mustangs’ 34-9 win in Bethesda.

Williams threw for 282 yards, completed 28 of 37 passes and tossed one interception. He made up for it by picking off a Georgetown Prep pass and returning it 81 yards for a touchdown with less than three minutes to go to seal the win.

Williams scrambled out of an often-collapsing pocket time and time again, rolling wide or stepping through the Georgetown Prep line to complete difficult passes in key situations.

The Mustangs converted 7 of 12 third downs, and on five of those conversions, Williams completed passes for 10 yards or more — and one went for a score. He also converted a fourth and 21 into points, finding a wide open Camari Murray for a 24-yard score.

But Williams, too, seemed more concerned with how he and his teammates ended up in those challenging situations than how they got out of them.

“We got in trouble. We made mental mistakes . . . we can’t have that out here,” Williams said. “We can’t have those errors moving forward and playing in our conference.”

Unless, of course, Williams keeps bailing them out.

At one point, the Mustangs took two straight false start penalties, setting up a third and 13. On the next play, Williams scrambled and found receiver Jordan Crockett for a 13-yard gain.

“I say we’re lucky,” Goganious said. “We had 15, they had five (penalties). That’s a very good football team and we just had a little more than they had tonight.”

Murray was Williams’s go-to weapon, catching eight passes for 115 yards in addition to his eight carries for 18 yards. Crockett caught five passes for 95 yards.
