Munstermen love to maul and their grip on the Heineken Cup might well have been loosened as a result of the ELVs that permitted teams to collapse the driving maul.
But now it is back and McGeechan has picked a set of forwards with an average weight of 18 stones per man to open the tourists' account against the combined Royal XV.
"If you think this is a big pack you should see the other one we had in training," quipped McGeechan at the team announcement press conference.
There are plenty of big men to follow in the giant-sized footprints of the first pack on tour and players like Gethin Jenkins, Euan Murray, Donncha O'Callaghan, Ross Ford and Phil Vickery are all set to be unleashed against the Golden Lions at Coca Cola Park on Wednesday night.
"Everyone will have got onto the field by the end of the second game and everyone will have had a start by the third fixture," said McGeechan.
So, what can he expect from the first game? Nerves, a bit of rustiness, but also a huge desire from his players to combine well together and push their credentials for a test place.
"There has been a lot of preparation over the last 12 months and a lot of work with the squad over the past two weeks. Now we want to learn from games we are playing," said McGeechan.
""We wanted to see players who haven't played much before at this level. We are looking at combinations over the first six games before we get into the Test series.
"We know a little bit about the Griquas, who won the Vodacom Cup and provide 11 players to the Royal XV, but we are concentrating on how we want to play. That has been our main focus this week.
"I still get nervous before games and this will be no exception. I'm sure it will be the same for all the players, even Paul O'Connell, because this is a new Lions jersey they are playing for.
"The tour really comes alive when the players gather and after Saturday the games will come thick and fast."
The Lions have had little trouble in winning their opening fixtures on recent tours. They ran in six tires in 2005 in a 34-20 win over the Bay of Plenty, there were 18 tries plus 26 points from Ronan O'Gara in the 116-10 opening triumph against Western Australia in 2001 and a comfortable 39-11 win over an Eastern Province Invitation XV in 1997.
In fact, you have to go back to 1971 for the last time the Lions lost their opening fixture, against Queensland in Brisbane. There have been only four occasions in 27 Lions tours when the first game has ended in defeat, although three of those have taken place in South Africa.
Don't expect an upset, but look forward to a strong indication of how McGeechan and his coaching team intend to beat the mighty Boks.
