I'm happy with our back row as it is, a 6 (Wood), a 6.5 (Robshaw) and a big, ball carrying 8. However I'm too much of a traditionalist not to fear that the lack of an out and out 'fetcher' does make us weaker. Yes, Launchbury and Cole do a lot of breakdown work but, as we saw least year in the game that must not be mentioned, playing a back row without a 'real' 7 against a traditional 6/7/8 combo can lead to you being right royally screwed. Having a proper ball carrying 8 helps, as does having a more physical second lock in Lawes or Attwood (in place of Parling) but I'm still not convinced.
I do like to think its a sign of how good a player Robshaw is that he has ended up being so convincing while playing out of position.
In an ideal world, most back rows have a player who is generally recognised by people as a 7. The skillset associated is so very useful that the ideal team will pretty much always have someone who has it. However, there are other ways to get that your skillsets in and ideal worlds are so rare that I feel you see very few traditional 6/7/8 combos these days. Debatably Wales were the only team in the tournament playing that model.
Certainly, as already mentioned, the lack of a standard openside was not the issue that day.
Oh. Yeah. Centres. Meh. Pick two, let the pack win. Simples.
What I would say is that Joseph's probably not getting anywhere. It's a shame, he has talent, but Lancaster has a clear preference for big centres so Joseph, Eastmond, Trinder, Daly... are all probably out of luck. Its one of the reasons I'm really in favour of Daly at full-back...
