I think it should.Should form only relate to player’s performances on Warriors jerseys , examples include Mathew Ridges best football was played at Manly, Tate at Broncos, Wiki at Canberra, Hoppe at Canberra , Vagana at the Bulldogs etc
If your choosing a "best of" to me it makes sense its based on their performances for that particular team.....however depends on the individual i guess. To some a players career performance is of more importance. Where that falls down for me is that i would be loathe naming Dennis Betts in a Warriors all time 13, yet career wise he's one of the most celebrated international 2nd rowers to ever be on our books and is probably justified to be named in the best ever Warriors side if we're using that criteria.......never mind the fact he was pretty kaka during his time here.
(incidently i thought Sean Hoppe's first 2 seasons here were strong enough to have him in contention at least for 1 of the wing spots.......however Manu and Meli are my picks)
