"Telling" and "looks as though" is not proof but people are quite happy hang the guy. There is no WC, AFL or legal requirement for Cousins to be in rehab at the moment. Who is to say that he has not just gone OS to see some friends and that the media have decided that he is doing rehab and now all of a sudden he has "lied to everyone".
All that is happened is that the WC have sacked this guy on assumption and if he sues they know they'll probably lose and have to pay him money that will fall under the cap and that is why he is still on their list. The AFL want to get at him with bringing the game into disrepute, but is refusing a test from a patrol car sufficient? Probably not....try being convicted of drink driving (shultz) charges of assault (krakouer, Voss etc), sexual assault (St Kilda) and I don't recall any players being kicked out of the AFL.
If he takes this line and if he doesn't actually get caught on or with drugs in the meantime, he'll play football next year and I know where I would put him.....smack in the middle of the MCG in a Tiger jumper.
Go Tiges!!!
