"I don't usually like to throw myself under the bus too much, but that [being the weakest link] is a real possibility."
McCaw said touch was never his strong suit because he "wasn't that fast" and didn't have that much of a step. "We played a wee bit when we were obviously playing rugby ... and I was probably better when everyone got tired and the fitness started to come into it."
While the Tap Blacks took an early lead, Arrowtown fought back, with just one point in it, 5-4, at half time.
With about two-and-a-half minutes left in the game, Arrowtown's Millie Eaton touched down, putting her side in the lead, 10-9.
But just on fulltime, Alley showed her skills to even the score, putting the game into overtime.
After just over four minutes of overtime, the Tap Blacks struck again, walking away victorious with the score at 11-10. It also ensured McCaw emerged dignity intact after his new fitness regime, which includes mountain biking and training for next weekend's 21km Tough Mudder in Auckland, paid dividends.
