I wrote a great post and can't be arsed to retype.. so Ill keep it shorter this time.
I don't think we are done with the Grigores of life yet, there's still Ricardo Grigore from Dinamo
Regarding the future CBs, there's Farcas, Pascanu, Boboc, Dima, C. Baluta, etc who looks promising, but not for some time yet.
In the nearer future, thinks look tougher with not many great CB options playing regularly. The younger players we have Balasa (at least he was finally called, hopefully used), Nedelcearu, Tiru, Hodorogea, Horj, Miron, Manea (more RB), Marc.. for older, there is Larie, Gaman, and Tosca instead of Grigore and Moti types, not great options but still better. There's (even younger tbh) guys like Harut and Ghita who don't get any minutes in Liga I though.
And if Gardos ever recovers from his disaster, even in a smaller league and plays ok, there's that.. but I have doubts.
Probably in the next 1-2 years, we could see our options something like:
Chiriches, Balasa, Tiru, Nedelcearu, Horj, Gaman, Farcas/Pascanu (unlikely but even Manea got capped at 16..)
For RB btw I think behind Benzar we could maybe look at Mogos (Ascoli)
