Do you ever read back what you write? Who says Miller doesn't have belief in this guy? If Miller doesn't believe in his players then the first step would be signing different players, which he's doing. He's also just signed an Olyroo - is that not a player with a view to the future? Isn't trailing another youngster a view to the future? I don't understand what you actually want, aside from something to whinge about.
And why is a bandaid solution a bad thing at this point? If we can finish this season with some level of respectability, the players won't be demoralized, and the club will have a marginally better chance of attracting marginally better players and we won't be left with another wooden spoon. Either you're a really angry person which you should probably do something about or your shtick is getting as stale as our club.
