But despite this competition within the reigning Aviva Premiership champions' squad, Trayfoot has still managed to get game time both domestically and in the Heineken Cup - making his European debut with a 14-minute appearance against Zebre in December.
But it is in the LV= Cup where his talents have really shone, starting all four of Quins' games as they booked themselves a semi-final clash with Bath on Saturday March 9.
His performances in the back-row led Trayfoot to being nominated for the Breakthrough Player Award, won last year by Gloucester Rugby's Jonny May.
And while he insists his focus is solely on downing Bath to reach the final, having got the better of them 21-12 in the group stages, Trayfoot admits that last year's recipient of the gong, as well as rubbing shoulders with England chief Robshaw, means he has no intention of slowing down any time soon.
"It is a real honour to be nominated for the LV= Breakthrough Player Award as it is a big deal for young players like myself," said Trayfoot, who is up against Bath's Tom Heathcote, Saracens' Ben Spencer, London Irish's Marland Yarde and Sale Sharks' Tommy Taylor.
"Jonny May won it last year and he has gone on to do amazing for Gloucester this season and it shows the competition, not just the award, is a great platform for young players.
"Other guys in previous years have wont he award and gone on and really pushed forward so hopefully I can do the same.
"It has been great playing in the Aviva Premiership and the Heineken Cup this season and I knew that with guys like Chris Robshaw in the team I would have to take my opportunities when they arise and I have been happy with what I have done.
"Chris is a really good bloke and a really good captain and he is easy to talk to about playing in this position.
"He was in my position five years ago having come through the academy and hopefully in for or five years I can be at his level too."
Since claiming their first-ever top flight league success last season, a winning mentality has arisen at the Stoop, and Trayfoot is eager to get in on the action.
"At Harlequins we have the squad to win every game regardless whether it is in the Premiership, Heineken Cup or LV= Cup and we all want to do that," he added.
"We want to beat Bath and lift the LV= Cup to get the first piece of silverware for the club this season so we can push on and win more."
