As much as I love watching Smashley, I am not sure he has the pace and fitness to play top level Rugby on a regular basis. He does seem very settled here and I wouldn't be surprised to see him take on a coaching roll whilst remaining registered as a player.
Re. Matthews, given what some French owners can be like, I'd want to be very sure I was making the right move if I wad planning to move my family to France and would want to go and see the club and town/city before signing. I wonder if he might stay for another season due to the Covid-19 situation.
I get the feeling Brad will stay. He seems to be really involved in the team socially as well as on the pitch, and kick started the #MakeThatCall campaign. Just a hunch but I'd be surprised if he left and think it would have been announced by now.
