The Greytown skipper readily concedes, however, that it wasn't until about the third round of Tui Cup qualifying play that he started to seriously believe they could go all the way.
"I remember we had a close win over Marty [Martinborough] and I thought then that it was on," he said.
Simmonds is quick, too, to emphasise the importance of the support of Greytown fans, especially during the grand final where they made up a good portion of what was a large and vocal crowd.
"They have got right behind us and the boys really appreciate that, it's played a big part in us getting to where we have. Everybody has been so positive, it's been terrific."
Greytown's win gave Robertson his third premier division title as coach. He was in charge when Greytown won in 1992 and helped John Pereira coach East Coast to the premiership in 2008.
Four other finals were played at Memorial Park on Saturday, Pioneer beating Carterton 14-10 to take the Hodder Steffert Cup premier division plate, Rams beating Puketoi 29-15 in the Shannahan Cup senior seconds decider which went to extra time, Carterton edging out Bush Sports 14-13 in the Ryan Cup senior reserve grade and Rams beating Eketahuna 15-10 in the President's Cup senior reserve plate match.
