Nottingham director of rugby Glenn Delaney says squad depth will be crucial going into the latter part of the season.
The Green and Whites secured a quarter-final British & Irish Cup spot with a 23-16 victory at Currie at the weekend.
Delaney said: "It's pleasing to know that we've got a squad with the depth to be able to challenge on all fronts.
"It's a credit that they are maintaining the level of performance desired to keep our momentum going."
Ollie Taylor, Jack Cobden - making his first start since September - and Jonny Baird scored tries for Nottingham, as they kept up their 100% record in the group stages.
The result continues Nottingham's recent good form, with eight victories in their last 10 outings in all competitions.
"It was a good performance against a very determined Currie side," Delaney added.
"The young lads in the team have really thrived in the competition this year and they have deserved the victories for the way they've played.
"Ulster have also been performing well in the group, so we'll see how things play out.
"Whatever happens with the quarter-final draw, we'll be confident of our ability to put in a strong challenge to continue in the competition."
