There's a couple of posters on the DW site that were grumbling in the summer (even before the new players had played) and ever since about the signings, plus there still a few that haven't quite grasped that Cips leaving was probably more to do with him hedging his bets (about Eng slection), rather than Wasps not wanting him.
I think all the championship signings have done well and will only get better. We've not seen much of Atkinson since the first few games, but I thought he did well when he played as well.
The one curious signing is Ambrose Curtis. I don't suppose he can be too happy moving to the other side of the world to only have played one game a third of the way through the season.
