There are, I think, a few questions that I would ask in terms of whether you'd pick Carter as a centre in the Wallaby squad:
1, What attributes do we want a 12 or 13 to have?
2, Of those attributes, which of them does Carter possess?
3, Given that there are only a finite number of places for centres in the squad, how does Carter compare to the blokes competing.
What do we want?
Deans seems to prefer quick, ball playing inside centres and straight running, incisive outside centres who are strong defensively. Carter doesn't really possess the Deans preferred skillset for 12, but maybe does for 13.
What does Carter do well (and not)?
From the stats, it appears that Tom is solid defensively, can truck the ball up into contact and provide a presence at the breakdown (i.e. help secure or steal the ball in the tackle area). He doesn't offer much in the passing, line breaking, creativity (a nebulous term) or offloading departments. I suspect he doesn't have a boot to speak of, but that isn't captured here. His other problem in my opinion is his discipline. He gives away penalties and has been known to get into off the ball niggle with the opposition. In big games in the knockout stages of World Cup's, team discipline is very important and I'm not certain he has it.
How does he compare with his competition?
Adam Ashley-Cooper is the incumbent at present and deservedly so. His form in the 13 jersey was outstanding in the latter part of last year. I don't think Carter would challenge him for a starting position. As far as backup, we can probably make the assumption that Horne is gone as an option. That leaves Ant, Cross, Morts, Inman, Chambers and McCabe as his competition. I would say that Ant and McCabe are ahead of him as outside centres at the moment, but he compares well to the other guys.
I wouldn't be taking him, as I feel that other players offer more.
