God I hate Phil Davies. I very much dislike him deflecting blame onto his players, even if it does hold some truth. Be a man and hold your hand up and admit that as the head coach the buck stops with you etc. Let the players themselves talk about blame on their shoulders.
Ultimately it's his responsibility to get the team playing as a cohesive unit, and the Blues look like anything but, especially in defence. The defensive coach they have in place is obviously not up to the job, and as Phil Davies was there when he was appointed, he shoulders the blame for appointing someone with no experience in rugby union.
If it were my decision, I'd get rid of all the coaches at the Blues and start again from scratch. If Shaun Edwards is available as a defensive coach, then jump at the opportunity. There have also been rumours of Iestyn Harries as attack coach, which could work well. As for head coach, just someone with a proven record (unlike Phil Davies). If a big name isn't available, then I'd be tempted by Dale Mcintosh as he would bring a no-nonsense approach.
Honestly, I'm getting sick and tired of talking about the desperately poor quality of coaching at the Welsh regions. One win doesn't change my mind about the inexperienced bunch at the Scarlets. I am still undecided about the coaches at the Ospreys, but after the last two weeks I am asking serious questions. The Dragons have the best bunch atm.
