The Rivercity Scrap Metals-sponsored Castlecliff Scrappers are a mix of older and younger players and went through the competition unbeaten until Saturday.
However, the Scrappers did draw with WHS in an earlier league match before going down 5-0 to the same side in a James Cup clash.
The James Cup is played in a handicap format and WHS went into the final against Collegiate with the latter enjoying a 4-goal buffer. WHS won the match 1-0, but that was not enough to claim the James Cup.
Smyth said his young team were all school students ranging for Year 10 to Year 13 and while he was set to lose a few of his older girls, he was hopeful of retaining the services of the younger brigade next season.
"Some are set to leave school, so we'll lose a few players, but the younger ones have played excellent football all season and hopefully they will be available for the next year or two," he said.
"Young legs have helped through the season, but so has the skill level and their ability to stick to game plans - they're a well-drilled side."
Smyth also thanked the side's sponsors and the players' families.
"Sponsors New Zealand Computer Solutions and Hyland Shearing have helped with tops and jerseys and that type of assistance takes the pressure off," he said.
"The parents have also been outstanding in their support throughout the season."
