you are right, lock and prop are similar however if they want parker to play 10 then it will affect his game immensely. Instead of taking 3rd/4th tackle hit up he will be expected to take the 1st/2nd which will result in more crash and bash rather than 2nd phase which is parkers best attribute. Also his overall size isn't suited to a traditional prop power game. They tried it with thaiday last year and failed so I ask hook and his cronies not to waste another players talent for this year. The overall defense needs a serious overhaul, and one thing I reckon that is really missing is a good old fashioned hard man in the squad, someone to intimidate in both defense and attack. The current squad really doesn't have a feared player, you look at some of the other top sides, roosters have hargreaves, bunnies have burgess, sea eagles have watmough, titans have bird, sharks have gallen/fifita, storm have harris, knights have jeremy smith, cowboys have taumololo/sims. I know some of these guys are douche bags but they carry an intimidation factor.
3 edge back rowers isn't going to work as well, I have never been a huge wrap on Glenn as he is very one dimensional and plays single corridor footy. He sits on the left and if the ball doesn't come to him he wont go looking for it. The team needs footballers and not robots who follow the coaches direction to the letter of the law each week.
