Who will stop the dominant Penrith Panthers?

Penrith Panthers have dominated all senior levels of rugby league in 2022, in an unprecedented performance. With the club building an extension to the trophy cabinet at Penrith the question arises: When will this dominance end?

In April they started their run of success, picking up the under-19s SG Ball trophy. They followed that up by winning the NSW Cup and under-21s Jersey Flegg competitions last week. On Sunday they completed the set when their NSW Cup side took out the State Championship by beating Norths Devils, before the first grade side stomped all over the Parramatta Eels to win back-to-back premierships.

They failed to win the NRLW, but that probably had more to do with them not fielding a team. Look out when they do.

"It's honestly hard to explain how good that feels," Panthers coach Ivan Cleary said of the all-grade dominance after Sunday's win.

"Because it can be gone. Four of those titles (across all the grades), there are grand finals to play. Sudden-death semi-finals.

"You have to have a bit of luck too. The footy gods have been on our side. That's awesome."

Next season the first grade side will chase the NRL unicorn of a premiership hat trick. The betting market has the Panthers favourites already, and there is absolutely no surprise in that. They lose some quality players in Viliame Kikau, Apisai Koroisau and reserve halfback Sean O'Sullivan, as the salary cap takes its necessary bites; but the Panthers have proven there is a long, very successful production line waiting to fill any holes left by these departures.

At the end of last season they said goodbye to the Dally M Centre of the Year in Matt Burton, but the team barely missed a beat as youngster Izack Tago stepped into the breach. Scott Sorensen and Spencer Leniu played off the bench in the Grand Final and either could comfortably step into the edge-running role of Kikau. Mitch Kenny started the Grand Final in the dummy-half role, while Soni Luke showed a lot of promise in the NSW Cup team.

Still the reality of player departures hit coach Ivan Cleary this week.

"I got a bit emotional yesterday, I don't even know why, I think it's just because this team won't stay together," Cleary said after the game.

"We've done so well for so long and I thought anyone can win on the day and anyone can win any game. I just wanted it to go well on the biggest night and I honestly couldn't ask for anything more."

Their first grade team is bristling with Test representatives and State of Origin players. They managed to navigate the 2022 Origin period, hardly skipping a beat. They'll come back from the World Cup in England with more experience and more confidence.

With Nathan Cleary and Jarome Luai continuing to build a dominating halves combination, behind a bulldozing bunch of forwards led by Moses Leota, James Fisher-Harris, Liam Martin and Isaah Yeo, it's hard to imagine who will stop them.

Penrith didn't just win competitions across all levels, they were absolutely untouchable in first grade. They could afford to slip a degree or two next year and still be too good for those in pursuit. It's an intimidating prospect, one that will have all the other clubs scrambling.

"That's how our club works," Cleary said of the Panthers' production line.

"You know, that's how we're going to, for us to be any good (going forward).

"We have to be able to do that.

"We have a lot of people that are in pathways and a lot of that who have worked so hard and don't get any credit."
