There is this fallacy that non-power clubs can improve by recruitment.
It just isn't the case any more - TPAs have ruined that.
Witness the Dogs and Broncos signing everyone of quality available while already over the cap - and the likes of Newcastle unable to sign anyone while far below.
I know you are feeling burned by the system at the moment, and I sympathise. And I agree with most of your sentiments about the unfairness of the NRL.
But the Tigers can improve, and can do it with smart recruitment.
The Sharks managed it, and we have no special advantages over the Knights or Tigers.
There was some luck, and some gambles, but we did recruit our way to a pretty decent squad, and coaching and cohesion have probably helped each "ok" recruit become a great contributor.
We got Fifita, Lewis, Barba, Heighington and Ennis as "rejects". Lewis was "headhunted" by Flanagan when struggling at a struggling club, as he knew he could provide a professional example for the squad.
We took a punt on Graham getting better, Panthers didn't want to lose him, but didn't want to match our offer.
Similarly we punted on a kid, Bird, who went on to be a great rookie.
Maloney was crucial, he was on the market and we put in a good offer for him. Townsend wanted to come back to us for family reasons but has kicked on well.
These were all pretty solid recruiting decisions.
Then we turned Feki (from junior warriors squads), Beale (fringe and unwanted at Dragons), Prior (same as Beale, people laughed when we got him), Bukuya (travelled to Warriors, then back to us when he didn't set the world on fire in NZ), and Tagatese (another jorneyman) into pretty decent first graders.
Leutele and Capewell have come through from interstate and have been great for us, and Holmes also but through our junior ranks and doing great. Brailey now seems to be going well from our juniors.
So we didn't really recruit any superstars (other than Maloney, but he wasn't really chased that hard by other clubs, and he was virtually a swap for Carney position/cap wise, but definitely an upgrade), just some good/talented players who became great, and some unwanted/juniors from elsewhere who have kicked on well.
There was some "luck", but also look at who we went through- Pommeroy, Beau Ryan, Jeremy Smith (great for us but Lewis was a like replacement), Ayshford, Robson, Matt Wright, Johno Wright, De Gois, Mick Gordon, John Morris, Gardner, Gibbs, Stapleton, Kyle Stanley, Mitch Brown etc.
Most those guys put in, but really the only established great players we bought (and didn't keep) from these were Carney (on his 18th chance, and he blew it) and Jeremy Smith (and Gordon was an established solid player). We also got those great "rejects" I listed earlier, but look who we had to go through to get there!
We just cycled through players that weren't good enough, slowly getting upgrades, and our squad now is nothing like, say our 2014 squad (with a few crucial players the same), and is also considerably stronger.
