Mostly agree with this. The main issue for the defence for three quarters was delivery in, plus one or two players. Hawkins is going to take players apart when the ball is coming in strong, and Hurley is still rusty. I'd have liked to have seen Ambrose on him, but I don't see that as a long term issue. Kelly and Bags also stuffed up quite a bit. Kelly I suspect that was just an off-day (he was fine JLT1/late last year), but Bags is more of a worry. He wasn't at his pre-2016 standard last year, and appears to have taken another step back. Hopefully it is just a slow start, but he was appalling on Sunday. But other than that, given how clean the ball in was, the defence didn't do too badly.
The midfield is where we have real concerns. We weren't missing anyone on Sunday other than Leuy (which will be a problem for a while) and got beaten. We did alright in H1, but I think they still had more I50's. In H2 we got trounced.
But the real issue isn't how many we lose. Its when we lose the clearances the other team is often so clean about it. All three JLT matches had periods where we not only got dominated in the clearances, but they were clean takeaways. We have to figure out how to stop this. And an extra man in defence isn't the solution.
