No you need a mixture of both to be a good player.Oh yeah that's right we need more players like Blair, young, Sinclair, goldsack.. Those are the kinds of intense types who win your premierships. Football skill is overrated good point.
In any case, every coach or credible football person would take the player who has better intensity/work rate but questionable ball skills over the bloke who can kick but is soft/doesn't work hard.
