Dave Tyrell would absolutely have been worth $250k / season back in 2014.
Still reasonably young back then, hadn't been a forward for that long and had improved every year up to that point. Ok, he'd never been a big metre eater but he knew how to find his hands and feet and deliver a quick play the ball, he had reasonable lateral movement back then and he tackled almost everything that moved.
Thing with Dave is that his knees have come into play earlier than anyone would have liked.
In the NRL though, if you're a starting front rower or at least in the rotation every week then you're earning at least $250 - $300k.
Up until this year, Dave was at least always worthy of a bench spot. He's had a fairly rapid decline though.
