I'm not so sure about the strength and conditioning that goes on in the club. Admittedly, there are some pretty impressive quads, pecs (etc) but I'm not sure this equates directly to the game as it has developed - maybe rugger, maybe just in those bash/crash zones, I'm not convinced.
Some players - and Eddie Betts is a great example - play really well on a pair of durable chicken legs. Stevie Johnson has a body like a worn out insurance salesman. When it comes to Harley, I reckon he's more like Eddie and shouldn't be bulked up too much. In my thinking, maybe they've gone for too much when what he's got is good enough.
Not sure - either way he was an excellent get, he's got heaps of talent/skill and this latest injury only sets him back a week or two. No need to spack-out over it, it would be demoralising to have him in the team (as they're going at the moment anyway).
