I actually really enjoy reading Claw's posts. He can obviously be pretty negative at times, but often constructive also. And he knows more about footy in WA than many of us.
Having met and spoken to JON, I think he has a terrific attitude (as has Richie Tambling).
We all know he's really quick, as his draft camp stats showed (and so was Pearce's, why didn't we draft him with a late pick?). But seeing JON playing for Coburg, he is really quick, especially for someone 6'3''. You know the 5'10'' players are quick when their legs are really going, such as Whitey, but you don't realise straight away with JON, because he's much taller, but then you realise that he's literally running away from his opponent and you know he's quick. A good example is in the Essendon-Dreamtime game, near the end where JON kicked the point. He ran away from his opponents then, very quick.
The darksiders could then (rightly) point out that he went on to kick a point, and he's not a very good kick. I'll admit, from watching him at Coburg, his kicking does need improvement, and I'm sure the coaches are working on it.
Anyway, from last year's draft, I think JON has just about the most upside. If he can get bigger, which he certainly needs to and will, and improve his kicking, he'll be a great player.
