On the pitch, the 30-year-old and his confreres have paraded a mixture of glamour and grit to thrash some opponents and squeeze past others. Off it, Henderson has been planning his wedding, which happens later this month, and it goes without saying that he has had to juggle his priorities in a diverse variety of roles. But here we really do have a case of somebody who is preoccupied with union matters.
It probably helps that he has grown up, surrounded by the smell of Ralgex, the bish and bosh of the scrum and the cherished camaraderie of grassroots sport. His father, Jim, was past president and coach at the Aurs Road organisation, prior to moving on to Ayr, and it seemed the most natural thing in the world for Henderson to pick up the torch when the opportunity arrived. By his own admission, last season wasn't an auspicious campaign for Whitecraigs - "It was a definite blip and we all knew that we had to step things up," he says, in matter-of-fact fashion. But their resurgence has been sufficiently potent for the Glaswegians to lead the division by one point from Cartha QP, two from Marr and three from Falkirk, to where they venture on Saturday.
Life in the lower echelons is a hazardous pursuit for characters in Henderson's mould; a milieu where they have to scrap and forage for every ball and where wafer-thin margins exist between the best participants. "It is dog-eat-dog, no doubt about it. Nobody does anybody else any favours and there is precious little between most of the sides," said Henderson. "We kept hearing that West of Scotland were struggling badly, but they came within a whisker of beating us, they were leading until the last minute, and although we eventually came away with the win, I am honest enough to admit we were lucky.
"We had a convincing [69-8] victory against Ardrossan on Saturday, but elsewhere, on the same afternoon, Falkirk were thumping Cartha [43-21] and Hamilton were just beating Marr [38-31], so we appreciate how tight it is and I don't think things will change for the rest of the winter. Everybody wants to gain promotion to the Scottish National League and nothing will be decided in 2013, so we have to push harder and harder.
"We will know where we stand after the next two fixtures, because both of them are away to good sides [Falkirk and Cartha] and these are the sort of matches where you have to grab your chances and make sure you come back with something. But at least we know we have defeated all these teams, and we have a group of players who have risen through the ranks together, so they believe they can challenge for a place in the SNL.
"They are not just team-mates, they are really good friends, and that makes a difference. One of the reasons we got out of jail against West was because the lads didn't want to let their pals down. It is terrific when you have that kind of spirit in the club."
Henderson is conscious of the many imponderables which can afflict a trophy-chasing ensemble. Whitecraigs have an impressive range of facilities, and ambitious officials, but it only requires the injury list to mount for hopes can be dashed.
"Ideally, we will keep this squad together and move up to the National League, but talking about it doesn't put any points on the board," said a pragmatic Henderson. "The Premiership might be a step too far at the moment, but not in the future. I have still got a few years in the legs yet, much to my future wife's annoyance. But coaching was always the plan."
