Players like SBW only care about themselves, not the team and not the sport. I have no interest in these players. I do, however, recognise that, if anything, it will become more common, but that doesn't imply one should agree with it, or like it. I also don't believe that showing a decent amount of loyalty and making a good living are mutually exclusive.
I think this is patently untrue. I think SBW has become the ultimate professional in modern football.
By all reports the guy trains incredibly hard, applies himself fully, gets on well with his teammates and is well behaved.
You only have to look at what he has achieved in a relatively small period of time in two sports to show this.
Early in his career he did a poor thing in walking out on a contract in the NRL, but since then. it's hard to say he hasn't given his all for every team he's played for and brought success pretty much everywhere he has played. I don't believe someone could do this without being entirely committed to his team.
