I think it's the work ethic that makes him stand out. He works SO hard, pressing, hassling, winning headers he has no right to win, going full throttle for 50/50 tackles, that when things aren't going his way, you're more likely to forgive. But when things ARE going for him, and you get the effort too, it's a sight to behold. Whether it's competition, or feeling like he's had a second chance after his injury nightmare, I don't know, but he's certainly grabbing his chance with both hands.
He's 29 next month, so in his peak really, and really I'm glad his latter peak years are now coinciding with a run of fitness and form, when he's had such a rough couple of years.
