I was being a tad cheeky with the Chase/Sinfield reference. The issue with his England form is much more down to the coach and the attack structures that he has (or doesn't have) in place. Wigan's attacking set moves are mostly designed to give Tomkins the ball at 3rd reciever with space to run into, which he can then exploit. With McNamara in charge, England don't seem to have any set moves whatsoever! Hopefully we'll see that change in the upcoming Exiles game but I'm not holding my breath. I have a degree of sympathy in that McNamara has a very limited number of training sessions to put systems in place, whereas at Wigan the timing and structure will get worked on on a daily basis throughout the season but even just a little attacking organisation and ball movement is much better than five drives for a crap kick

Another interpretation could be that he's not the finished article as a full-back, and perhaps never will be. The ability to judge and time a jump for a high ball is quite specialized and he'll almost certainly never be a Steve Hampson in that regard. If we're talking about the complete player as a full-back, I'd agree he's flawed, but as a player in general, his sum total set of abilities is up there with the best - nobody is the 'perfect player' ( apart from me of course, its just I got too distracted by women and drink to play professionally ). His tackling is actually very good indeed relative to body weight ( on that measure, Rob Burrow beats everyone )

Got a few bites

His positional play in defence when I have seen him is pretty good, he has always been there abouts when a Try is scored against his team (I am talking mainly four Nations)

He has not had the body weight or technique to stop several of those tries but points for trying.
The only negative has been a couple of incidents where he has been late and come over the top with his knees as he did with a try Morris scored in a Test last year.

That certainly makes a comparison with Slater fair then, he's always happy to put the studs in on a man trying to put the ball down.

Not in recent times Browny, in the past he tried to get his feet under the grounding of the Ball, that was some time ago and the Laws were changed in Oz to address this issue.
He has never been a player to come in with knees to the back as a player grounds the ball, he had that a few years ago himself in a Test with a length of the field try with some no name trying to injure him as he was over the line. Almost caused a fight at the time.
