His defensive reads where not the best (fullback is a very specialist position these days, they do much more then catch bombs). I think he will improve with more time under his belt. Perretts defence and bomb defusing is not great (he seems to catch the ball planted) which will mean he might get smashed at fullback.
We do have untested players to throw in there. But after coming away with the points tonight we might aswell keep the same 17 for next week. Good thing is there will be video of Morrises games and knowing how tactical Hasler is he will be able to review all his positional plays and Josh will be better next week.
