He had an off day today, but generally speaking Burton's boot is one of his major strengths. In terms of raw striking he's the only one who rivals Cleary/Reynolds, he just hasn't had time to develop the control those two have. His bomb is ridiculous, right up there with Nath's. He's got nice variation/deception in his short kicking game too. Easy to forget that Nath took quite a while to develop his boot too.
Burton's just suffering in exactly the way many of us expected him too. He's a kid with insane potential, trying to do too much behind a pea heart pack for a basket case of a club. Every half in the world would look worse there than they would here (or at any of the stronger clubs). Unfortunately for him, the RL world tends to forget that and as a result his hype levels are dropping in a way that will influence the level of his next deal. Tough to be too critical of a kid inking his first big deal, but I think he'll look back on this period of his life and wish he'd waited a while for an offer that didn't put so much responsibility on his shoulders.
