Harlequins full-back Ollie Lindsay-Hague thinks his side's strength in depth is a big positive as they return to Premiership action against Exeter.
Saturday's game at Sandy Park comes on the back of two impressive wins in the Challenge Cup pools, against Montpellier and Cardiff Blues.
And 25-year-old Lindsay-Hague believes it's his side's ability to rotate with little negative reaction that is an excellent sign heading into 2016.
"There is a lot of competition in the squad now, it is looking really strong this year," he told the Harlequins website.
"The strength in depth is fantastic and everyone has to make sure that they are playing well or there is someone from the second team ready to come in.
"We all keep pushing each other and that keeps the team fresh.
"Last year was very weird, we as a club are not used to losing all that much but it was nobody's fault, we didn't have that strength and that showed up.
"We want to win every competition we enter and the Challenge Cup is no different, we want to get our hands on that silverware.
"We have guys here with so much experience under their belts, but there are no big egos – every one of them is willing to help the younger lads – we have a great structure."
Quins' exciting brand of rugby has won many admirers under O'Shea's tutelage and Lindsay-Hague – equally comfortable at wing or full-back – has been one of the prime beneficiaries.
And after his try-scoring feats in Europe, the focus has returned to domestic matters and the versatile back is keen to continue to make an impact.
"It was great to get a start at full-back, to give Browny a rest and have a chance to show what I can do there, when you are coming off the bench it's a bit different," he added.
"I want to be starting those big games, whether that is at full-back or on the wing.
"We are playing a good brand of rugby, moving the ball quickly to the guys out wide and that has given us the opportunity to do some exciting things – it has been working so far.
"Considering the first couple of games of the season we didn't have our World Cup guys either it has been a really good start.
"Beating Wasps was a fantastic result – look what they have done against Leinster and Toulon since then – but it is only a start."
