that's all well Tony, the stats and all, but are you denying the effect Toulon has on all its players ? Menini was a fkng nobody, he's now in the xv de France and I'm not sure it's all just because he's seen more in the Var than he was in the Basque country. Barcella had lost all his mojo at scrumtime and nobody was talking about him anymore after those excellent 08-09-10 seasons. And yeah he played a couple of games this year, but have you seen him ? He was in Ulster in the Euro Cup and a top LH in every aspect, doesn't get much better than this. And there's no denying the move to Toulon has loaded him with envy and revived his career, I mean, I'm not sure what we're debating here.
Imanol looked poor every single time I watched Biarritz last season, he's on the verge of being selected again for France and regularly appears in mentions of the weekend's top players since at Toulouse.
All those ex-BO players are benefiting from new life in a competitive club again, there's no secret as to why we're seeing them thrive again (nor is there denying that they are).
