Short term - yes, it's better for the Eels not to make rep teams.
But long term.....I assume you've all noticed how much Hindmarsh has improved since becoming an Origin and Australia regular?
The benefits of having class players, in great form, like Grothe, Tahu, Riddell and Morrison play rep footy would see short term losses to Parramatta, but long term benefits too - which I believe are far more important.
And on Priddis, I think Riddell is more important. He plays for a winning team, he kicks goals, he makes great impact AND he can even play second row at a pinch.
Not to undermine Priddis, whom I rate highly.
