In fact, just 20 of the Pittodrie side's 41 league goals were scored by the Northern Irishman, but the feeling persisted among opponents that, if the striker could be quelled, then his side would most likely be, too.
This season, however, things have changed. Derek McInnes' team have scored 11 times in their opening eight SPFL Premiership matches with only three coming from the feted forward, who missed three games because of an ankle injury sustained while on international duty last month. In his absence, Aberdeen scored nine times in three games in all competitions as his colleagues proved a point.
That being so, McInnes had the luxury of affording McGinn a quarter hour of action in Monday's evening's draw with St Mirren but is expected to reinstate the striker to his XI for today's trip to Dingwall. "I've missed playing," he said. "But the team has played well and they have responded with good victories.
"I've always thought there was a spread of goals in the team. Scott [Vernon, who has scored four in his last three games] has always shown in training that he is a goalscorer. He just needed a break and when it came he took it. There wasn't a big spread of players scoring goals last season, especially from the strikers, but this year they are coming from all over the pitch. Peter Pawlett has been unbelievable. He's had a new lease of life and he's scoring goals and his performances have been excellent."
Given the manner in which Ross County have defended this season - they have conceded more than any other team in the SPFL Premiership - Aberdeen will surely be confident of adding to their tally today. However, McInnes side struggled in Dingwall last term and McGinn is wary of what awaits them. "We know that it will be a very difficult task," he said. "County have conceded a lot but on their day they are worth keeping an eye on. We struggled against them last season, especially up there."
Aberdeen are unbeaten in their last six and are seven points ahead of County but Derek Adams has also been looking at the recent meetings of the two sides and will use that to motivate his players. "We did well against them last season, winning two and drawing once," he said. "The teams are on a similar run of form over the last six games. Aberdeen have taken eight points and we have taken seven points and they just lie ahead of us in the form table. So it is two teams on form and doing well."
Brian McLean was substituted last weekend against Motherwell after being concussed but has trained this week and is available. Adams said: "I am delighted to have him back. He is quick, good in the air and was missed last week when he went off. I thought for large spells we played well, middle to front we are looking dangerous and we are scoring goals. We need to stop making errors that are causing us to concede goals."
