DCU produced a dominant second- half display to book their place in the last eight, but yesterday's clash with Queens was more noteworthy for those who didn't play.
On Tuesday evening, DCU received word that Cork's Aidan Walsh and Donegal's Michael Boyle were ineligible to play in third-level competition.
In the event, they were hardly required as the Dublin college ran out worthy and comprehensive winners.
However, that was of little consolation to an irate DCU boss Niall Moyna, who insists he has "no intention of promoting Gaelic games" after the introduction of a new rule relating to players' eligibility to play colleges football.
Both Walsh and Boyle fell foul of the new requirements, which limit the courses players can take and also the number of years they can play in third-level competitions.
"We were surprised and disappointed," said the DCU manager of the ruling from the Dispute Resolution Authority.
"Aidan Walsh made a decision three years ago that he was going to drop out of a course and retrospectively they have imposed a ban on him playing collegiate football.
"It's disappointing in a number of ways. That man is going out to teach physical education and I certainly won't be encouraging him to promote Gaelic games and I mean that. In my classes from now on, I have no intention of promoting Gaelic games.
"The retrospective application of the rule really annoys us. They were saying the rule was enacted maybe a year or two ago. But (Walsh and Boyle) still made their decisions three or four years ago."
The Monaghan man added: "Michael Murphy is going to be a PE teacher and so are Paul Flynn and Aidan. Why should they promote Gaelic games if that is they way they are going to be treated?
"Michael was disgusted. After the meeting he said that, if there was ever an excuse to give up Gaelic games, that was certainly it."
While the first half was competitive, DCU never looked like relinquishing their crown in St Clare's yesterday.
For a period towards the end of the opening half, Queens were in charge and, with an extra body around midfield, they bossed possession.
Having missed a couple of long range frees, Derry's James Kielt started to find his range from placed balls, but the Belfast side could never get their noses in front.
Moyna's side weathered the storm with Dean Rock making little of the windy conditions to kick two first-half points, while Murphy kicked the last point of the half to put the Dublin college 0-7 to 0-6 in front at the break.
It was fitting that Murphy would have the last say of the first half because the Glenswilly man was the difference between the sides on the restart.
From his new posting on the edge of the square, Murphy was unplayable.
He landed the first three points of the half, including an outrageous angled effort that, in the conditions, looked impossible.
"He's different class," Moyna said afterwards. "When you have someone like him on your team, he is the go-to man. Since he won the All-Ireland, he is a transformed player. The weight of the world is off his shoulders. He leads by example."
Other DCU players responded. Sub Chris McGuinness landed two points upon his introduction and Flynn also got on the scoreboard.
Queens were running out of ideas and energy and the strength of DCU's bench helped them set up a quarter-final date with UCD back in St Clare's next Thursday.
