I had a scary thought last night whilst thinking about Suli going to the Bulldogs. It was that clubs who back-end contracts have a massive advantage over those who don't.
If a team engages in this practice, adding a player to their roster on a heavily back-ended contract, it benefits them now certainly. But the downside is it is meant to restrict them in the latter years of that contract where they have less cap to manoeuvre with. Well, not if they back-end the next contracts also. Just keep back-ending them.
Sort of like a country with their national debt, but for a club there's no interest to pay, nor any limits or consequences.
The only hurdle I can see, is getting the approval of these contracts from NRL HQ, but that does not seem to be a problem for some clubs (e.g. Bulldogs with a lot of their contracts Eastwood, Graham, Morris, now supposedly Suli).
So why not buy a couple of $1m players right now on 4 year deals, back-end their contracts significantly, and keep doing it. Where's the downside?
