If Charlie can, whilst needing to work on his game management, help us overturn deficits to beat Leicester and Exeter, whilst also helping us beat Saracens and Toulouse, then I think he's on the right track.
Re. place kicking, Jimmy is now on 979 Premiership points for Wasps. Alex King is the only person to score more points in the Premiership for Wasps. I say let Jimmy set a new record, then give Charlie the role. It'll also give us an opportunity to give Mills some more game time as unlike others, I expect he will stay at Wasps.
