He has had more than enough time and more than enough chances. Sad thing is, he actually played a couple of real games of footy this year. Ran hard, tackled, presented well etc. It's just that he falls into his old ways given enough time.
I can not see Watts being anything more than "good" for us. Is good enough? You can only have so many of them in a team and given his ability to go missing completely, if his time isnt up, it has to be one an absolute knife edge.
