I think there's quite a few parallels between Wales and Ireland. Each team's most successful coach is retiring after the world cup, they both seem to be struggling with teams adapting to their tactics that have brought them success and they both gambled on out of form players who haven't really delivered. It was an extremely poor performance from Wales, if they were playing any other of the quarter finalists I'd reckon they would have lost yesterday.
There's too many players that are out of form for Wales, especially in the backs. Parkes is a centre who's reputation come from a solid player who did all the basics well and made the right decisions, now he's struggling to do those and has suddenly looked out of depth. With Wales only taking 3 centres, they don't have too much of a choice in this position, Watkin has shown a bit of promise but not really stepped up to the plate. Even worse is North, he looks like he is carrying an injury to be honest, doesn't seem to any pace or power at all. Gatland made brave decisions to leave Lee and Evans at home in the front row and pick in form players, but didn't seem to do this with others. It now looks like the wrong decision to leave Lane out, who probably was the inform Wales winger last year despite injuries. With Centres and Wing struggling more has been left to Biggar to get this backline going, however this isn't his strength and he is really struggling to get anything out this backline. This is where Gatland has to be brave and pick Patchell, he's a running threat himself and because of that will keep the opposition's defence a bit more honest and give the back a bit more time. Forwards have been pretty decent to be fair, however if that Navadi injuring is as bit as some are saying that's going to be a problem, especially since all Moriarty is currently offering is penalties to the opposition. If Navidi is out, then I would rather out an out of form Shingler at 6 with Wainwright at 8.
