I'm with Chunky, Brookes has to start - when alongside Taylor plus our best LH, we have a very decent front row which isn't something to be sniffed at!
12 is an issue - Jimmy is ageing - as are we all - I think MLB had a very hard first season when it would have been expected he would have had a gentle intro to the Prem with Jimmy first choice. He was, for me, burned out by having to take on the 12 shirt, next to a new 10 and a team rather denuded by injury. I think he will be ok if managed properly and had put in much better looking performances this season
Robson isn't fit, surely, leave him out until he is
As for the choices across the team, the pack has lots of decent options in front row and back row, I think we probably just need a little patience, but not too much, we need some Prem points. Exeter away, wouldn't be my choice of next game!
