Aidan Guerra believes as many as nine spots are up for grabs this season.
Having recruited well for 2019, competition is at a premium.
With Round 1 fast approaching, nothing is guaranteed in the NRL and for the nib Newcastle Knights, the incredible depth is a blessing.

Nathan Brown is spoilt for choice.
With several selection headaches ahead of him, trial games against St George Illawarra and Cronulla take on an even more significant meaning.
"I mean there is nine or eight positions up for grabs and probably 10 or 11 blokes contending for those positions," Guerra said.
"I don't think anything is set and I don't even know if Browny has got his mind made up yet and I guess that's what this next two-month block is and into the trial matches is going to make those decisions for Browny."
Guerra, who can play backrow or lock, finds himself competing with the likes of Mitch Barnett, Sione Mata'utia and Lachlan Fitzgibbon for a place on the edge.
Tim Glasby, David Klemmer, Herman Ese'ese and even Barnett are options to wear the No.13 with Guerra unsure on just how the team will shape-up for Round 1 against Cronulla on March 15.
"I think there are a few of us going at it there for edges and middles and even the makeup of who is going to be on the edge and who is going to be on the middle is still yet to be determined," he explained.
"We're competing every day for positions and just working towards those trial matches.
"... I have always said to Browny that I prefer edge and I have said to every coach that I prefer edge and I know that I am capable to play both and I can value add to a side no matter where I am.
"I've played a lot in the middle through my career, I've played a lot on the edge and I just try and do a good job at both of them."
