Welcome Ben, looks the goods for mine, love his burst out speed, tackling, very very very accurate foot passes, for those of you that have been around a bit does Johnny Platten ring a bell and not just because of the hair. 
For the most part he didnt seem overly quick but at about 1.40 into his highlights package he puts on a burst that seems impressive but its not fully tested because his opponents are not really interested in the chase. We have to wait and see. Kicking seems a feature but again 73kgs? If he gets to say 80kgs, does he retain his speed?
I don't think he needs to get to 80kgs Ramps. He is the type of player who will be defensive by his energy levels and elusive by his size/speed. Whether any of it is up to AFL standard is yet to be written to history but he doesn't really need the bulk, just the ability and intent.
Until he takes a hit that shakes his world 
Sh|t monk, that could be said about anyone, no matter what size. There's an old saying It's not the size of the dog in the fight, but size of the size of fight in the dog. I've seen big bloke get pushed around by smaller blokes simply through the way the different individuals go about it. Look at jhonny platten and even Liberatore (who i dont rate as a footballer but you could never question his endevour), blokes who were small but made up for it with other attributes.
I saw one of the Krakeaurs get bumped out the contest one day, only to bounce back up like a rubber man and straight back into it.
It's what inside that counts and some of the blokes at richmond get bumped/brushed aside moreso because of their mindset. Just watch the way they go about it and compare that to Nahas.
I'll go out on a limb and say that if this bloke doesnt make the grade, it will be because he is not good enough, not because of his body size. From the short clip he looks to have lots of endeavor and has very good hands in traffic. You don't develop that skill unless you spend a lot of time with the ball in that situation. Hardly what you'd expect from someone who constantly gets knocked out of the contest.
