The legend, though, provides an apt analogy to a triumph of perseverance.
His Bannockburn moment came after 52 minutes. Energetic, lung-busting bursts through Aberdeen's defence had already offered Quinn at least two clear chances before he made it count. His unflappability, particularly after one poor fluff, was impressive and summed up the broader grit and determination in the Ross County ranks. The positives for the hosts were abundant in this performance, with a valuable three points adorned by a welcome clean sheet and strong individual displays.
For Quinn, the thunderously-struck winner brought relief as well as jubilation. "It was nice to score - eventually," he admitted. "It was my second goal of the season and it was a great feeling. It was good to get another chance so quickly as the first one was playing on my mind a bit.
"For the first chance, I think I was already away celebrating before I actually did the important bit of putting the ball in the net. I am just glad the other one went in. The ball ran a bit further wide than I thought it was going to. I had to get onto it a bit quicker, but once I got the touch I made sure I hit the target."
The man who carved the chance was Melvin De Leeuw, and there seems to be real talent in the former SC Cambuur man's toes. Quinn is certainly an admirer.
"He was excellent," Quinn said. "That is the sort of thing he has in his locker and can bring to the team. Melvin has worked really hard [for his chance in the team] and has scored a couple of goals now. He brings a bit of finesse and touches on the ball that you cannot really teach - the sort you've either got or you haven't. He has definitely got it."
Quinn is honest enough to admit County were in need of a morale-boosting win of Saturday's variety. Good results have been interspersed with mistakes and disappointing setbacks to date, but there is obvious promise for the remainder of the campaign. "It has been up and down for us," Quinn acknowledged. "It is always important to win your home games, though, and just try to take something away from home. That is what we are aiming to do this season. The clean sheet is massive today."
Aberdeen were lively as play opened, but soon hit a brick wall in the shape of an assured County defence. Mark Brown, the home goalkeeper, had little to do even amid the desperate onslaught from Aberdeen towards the end. The frantic pace of the match hampered the quality of play, but County were increasingly the more dangerous side.
Great tenacity and awareness from young Steven Ross set up the best chance of the half. He showed strength with back to goal, then turned to drive on, eluding a couple of challenges. His slipped pass found Quinn to the right of the box but the County midfielder struck just wide.
The second period offered more of the same, with Ross unlucky not to connect square on goal after a fine Graham Carey delivery. County, though, had only to wait a minute for the breakthrough. De Leeuw's neat control and tremendous diagonal pass freed Quinn racing through on the right and he smashed his finish under the crossbar from eight yards.
Aberdeen went hell for leather towards the end but the visitors' solidity was impressive. Ryan Jack, who struck wildly at one of his side's few chances, cut an understandably solemn figure at the end. "We had a few chances at the end, but we shouldn't have got ourselves into that position in the first place," the 21-year-old lamented. "I feel like we have let a lot of people down, especially the fans. The fans were excellent, they were behind us the whole way, even from the warm up.
"To let them down the way we did was unacceptable and all the players are gutted. We let the staff down as well as the fans and ourselves. We had a lot of pressure, but we never started playing until they scored. It was too late in the end and Ross County got the points. All the players are gutted and we know ourselves we have let people down."
