Nope, not that easy.
May isn't a Todd Carney. Todd IMHO was actually someone I think we should have signed (1 year contract) when he finally got booted from the Sharks. Yes he would have stuffed up again, but we could have used him.
The Dogs have an experienced coach in ... Phil Gould and his assistant Ciraldo.
They can manage the attitudes of May and could manage a troublemaker. Xerri has performed under them and Xerri will get the boot if he stuffs up.
Marshall however does not have that support. Don't make his job harder.
