Could it be the fact his younger brother has the jump on him in the quest for a berth in the Hawke's Bay Magpies rugby team?
Or could it be the fact David Neilson's partner, Otane netballer Claire McGettigan, has more Hawke's Bay premier club titles than him?
"Yes a bit of both ... it's all contributing," Neilson said when quizzed on the motivational fuel for his hot form in Hawke's Bay's premier club rugby competition.
The Tanalised Napier Pirate Rugby and Sports first five-eighth produced his third player-of-the-match performance of the season at the weekend to become the 14th weekly winner as the battle for the Tui-Hawke's Bay Today Club Rugby Player of the Year award continued. Neilson's brother, Pirate second five-eighth Jackson Neilson, was in the Magpies' wider training group earlier this season and Neilson has yet to get that close.
"I was asked a couple of seasons back but I was living in Wairoa then and that prevented me from getting to all the trainings. But it's good that Jackson has been able to bring back some wider training group tips to our club environment."
