There is now a clear blueprint of what’s required to be an effective edge back rower, they ideally need to be a big bodied, athletic hard running tackle buster such as Kikau, Olakau’atu, Katoa, Nanai, Martin, Crichton, Fifita, Ben Turbo or the smaller but fast & aggressive players such as Radley, Young, Piakura, Nikita, Wilton etc
We are finally wising up and realising Samuela Fainu fits this description, but you need at least 2 more, one as the other starting player and one on the bench that can ideally also play in the centres should injuries occur throughout a game.
I’m sorry to say, but Bateman no longer fits this description and Papali’i although more than capable of breaking tackles, is probably a touch too slow of what we need.
The Roosters moving Radley to an edge looks to be a master stroke and Souths now realising Kalomatangi is also probably a touch slow for an edge and more suited as a middle forward is further evidence to be effective on an edge the player needs to be very fast and aggressive, or a big body that is also faster than average.
