McBean just needs to work on his core strength and tank, you don't want him bulking up too much....biggest asset is his agility and he'd likely lose some of it if he were to get too big.
you guys have seen a hell of a lot more of mcbean than me and normally i would bow to those who have seen him play a bit.
but yes theres always a but. the way he plays atm imo wont translate to afl footy. without size strength and power he can have all the agility in the world but it wont help him much at the top level.
if he cant compete in the air and take contested marks he wont make it. just to compete in the roles envisioned for him he has to get to 100kg and not lose too much of his agility.
me im hoping hes a david hale type or even an upgrade on zac clarke its in that role imo he can make the grade. so i suppose i see him more as a ruckman long termthan a kpp. personally and ive said it a fair bit i think if hes to play kp he should be played in defence.
