I do however, find it ironic how all the calls for player exhaustion seem to be coming everywhere but from the players themselves.
When, or how would any currently active player say this? It's really not in the best interest of most of them to ever even broach the subject for a few reasons.
I believe this is a fallacy perpetuated by SA scribes who have nothing good to write. The fact that the players are CHOOSING to forgo their off-seasons for stints in Japan simply proves it further.
These guys are lucky if they have an 8-9 year career. Of course they are going to take the offseason $$$ in Japan if it's at all available to them. They're all one bad injury away from losing their primary stream of revenue and they aren't exactly on NFL money to begin with so the lure of offseason dosh is enormous.
Making decisions in the context of future seasons isn't something most of these guys have the luxury to even think about doing.
I can't think of anyone so far who has done the Super Rugby-Test Season-Japan-Super Rugby roundabout and come back in better or even
the same form that they left in. It's a downward trend almost across the board and the common variable is lack of an offseason - same thing was happening before Top League contracts were even a talking point.. Rocky Elsom, etc.
