Players that will be still around in 5 years? Brown & Mansour maybe.
Hypothetically speaking it would be any of our 2nd longest serving players so probably a handful of blokes who came in at the same time. But nobody would be eligible for about the length of time McK's wrapped up for now (maybe a year or two earlier?). Effectively, we'd be getting a prop for next to nothing for that time.
The allowances certainly don't help Penrith as much as some other clubs, but this is a smart move given the circumstances just provided his form doesn't go backwards.
Edit: so, it's $200,000 for 8 years continuous service including Holden and NSW cup. I'm not sure who our 2nd longest serving players are, but it would be McK and daylight wouldn't it?
