I'd have to disagree. That whole bench is pretty much converted mobile backrowers, not a genuine "big man" on it. Clark obviously, Ale is a nuggety backrower playing as an undersized prop, Sifakula is a recently converted backrower who seems to have spent his whole rehab in the gym, Halasima is a centre/backrower. Maiu'u is is the most genuine prop there but even he is in the Ale/Afoa, shortish, nuggety and mobile mould.
If you want to get into the nitty gritty, I'm not sure there's a a guy on that bench legitimately over 6 foot tall. They all fit with a certain body type Webster seems to go for.
Yeah I see your point, but how many BIG guys are there in the comp? Over 115 kegs according to Zero Tackle, that's AFB, Paulo, Papali'i, NAS, Haas, Fifita, Pangai Junior, RCG, BHU of the established FGers. Not many to go around. Even Bunty is up there in the top 15 as a 112kg guy.
And Halasima has to be over 6 foot, surely. OK, his Warriors profile says 6'1. Does height matter so much, unless we're talking about offloading - which we don't do, anyway? Those guys I mentioned, no none of them are BIG but there has to be an intangible metric of how hard you hit the line. Best example I can think of is Michael Hancock, who wasn't a big guy but no f**ker would ever put him down 1st try. Same with Mark Telea in union.
