Hope things find a way to work out for him, can’t imagine a season at Agen in the Pro D2 is going to be much fun.
Given the way that the Pro D2 promotion works, there's no cast iron guarantee that they'll bounce back either!
If I've understood it correctly, it goes something like this...
1. The top two teams at the end of the regular season go straight to the semi-final.
2. Teams 3-6 play quarter finals, the winners of which go to the semis.
3. The winner of the final is automatically promoted to the Top 14.
4. The loser of the final has to play a play-off match against the 13th-placed team in the Top 14 to decide if they're going to be promoted.
So whatever way you look at it, there's a lot of opportunity for banana skins even if they "win" the regular season. Just look at how often Bristol "won" the Championship before losing the play-off final.
