not really true. The game has moved on from lumbering immobile big men, no matter how good a kick they are. I haven't seen him play, but I hear he's big, fast and agile, and a poor kick.
Its all about cost benefit. If other aspects are good enough to compensate for being a poor kick, and/ or if his kicking improves enough to be a pass, all good. I actually reckon pinpoint kicking is becoming less important, its still important, but the end of the Hawks and the Bulldogs flag signalled a chang. JJ just bangs it forward, and he's one of the hottest players in the game.
