Maybe not but he is getting consistently good results with just 2 big contract signings (Moses and matterson), a bunch of discarded players (mahoney, ferguson, opacic, Blake, RCG, Hipgrave), some astute buys (Brown, Lane, Sivo, niukore) and some young kids like Brown and kaufusi... and Paulo of course who he seems to have turned into one of the best props in the game...
Maybe the parra recruitment team deserve a lot of the credit and he may not have the past results that Des does but he sure as sh1t is not working with a team of Stewart's (x2),, Killer, Matai, Bell, Kite, Ballin, Watmough, Menzies, Orford, DCE, Foran, Hopoate...
Personally I have been amazed that Moses has developed the way he has and say what you like about Arthur but that team plays with passion and looks deadly with the ball...
