Yes, bur can you name me a player that Andrew Johns actually improved?
It seems that Joey isn't great at passing down his skills, and knowledge.
Barrett's coaching career, thus far, has been a disaster - but he's been credited for setting up some great offensive sides (by a few different people), so perhaps he'd be a better fit for Jake.
Only time will tell.
And it's probably a bit harsh to suggest a 20-year old is in the turd category, when he was clearly not physically ready to play First Grade, but was thrust in...
