We've been over this many times.
EOS underachieved for two main reasons.
He was Munster centric in his selections.
He didn't develop strength in depth.
MO'D compared to Cullen being the worst example.
He refused to select Miller Quinlan and Wallace as his first choice BR even once.
Lawrence Dallaglio critised him publicly for starting Costello ahead of Miller for example.
He didn't even use his substitutes well preferring to flog his first choice 15.
Etc etc. Thereby missing an opportunity to develop other players.
Oh and he was Long enough in the job to build strength in depth.
He didn't earn the right to criticise JS but like the rest of us he's entitled to his opinion.
In a positive sense he wasn't a great coach but he was a good coach.
He'd be ideal for Ulster right now.
