At the very least, one would think that Canterbury will not have an ounce of complacency in their ranks for Sunday.
McGahan has run well from fullback, combining well with the likes of Tevita Li and Nafi Tuitavake, scoring a try himself and providing the last pass on two others. But like the rest of the backline, McGahan is seeking the consistency to match the industry of the pack.
"I think our forwards have been the mainstay. We are a bit patchy as a backline."
The addition of Walter Little as technical advisor has helped, a new voice from the Glenfield coach and one who played a record 145 matches for the union. His expertise appears to be having a positive influence on the passing and lines of the backs. His son Michael has emerged as one of the finds of the season with his wide skillset and four tries.
"The belief is a big part of the games we have won. It's just individual errors that are letting us down. There is belief in the potential that if we put it all together for 80 minutes then we can really open some sides up," said McGahan.
The short turnaround after Wednesday night's 39-20 defeat to the Tasman Makos will be not be used as an excuse.
"You are tired and you are sore, you just have to get on with it. They can't change the draw."
McGahan himself doesn't have to play with the pressure of a contract, having signed with the Blues for 2016 even before the ITM Cup kicked off.
