You are wrong De Ceglie had been available for more than 50% of the season and CR had many many opportunities to use him, but he didnt, because he already made up his mind about this position.
CR gave some very very limited playing time on DC, mostly as sub and as a starter, only because he had no other choice.
And up until now he has done the very same thing with Giovinco too, i cant believe that ppl have so easily forgot what has been happening for the whole season, when Neddy+Moli were used for the whole 90' even when we had to play 3 games/week, despite having both Giovinco and DC both fit and available on the bench!!!
And i am sure that he would have done the same thing with Marchisio too!
CR considered Moli as our first choice and DC as a squad player, LB/LM joker.
On the other hand, i think that he rates Zebina higher than Grygera (naturally)
Which is a whole different case, since Zebina has been indeed out injured for the majority of the season!!
CR has claimed with passion that Molinaro has been our best player last year and it is clear that he is his personal favorite player.
Even if DC or Criscito will show more promise than Moli, CR will def not see that, because he is extremely biased with that player.
He has already shown that he doesnt tolerate Criscito's non perfect performances.
By the time Criscito arrives, molinaro will be our permanent starter, being our main man for 3 seasons!
The amount of playing time, confidence and teamwork that develops through this whole period of time, can hardly be overwhelmingly overthrown by 15' or so of playing time Criscito might have, when he will be called to replace Moli as a desperate solution to a game the rest of our team will be already failing...
And even of Criscito manages to perform a far better performance than moli,
despite being a younger player, who was already introduced to this team.
It still wont be enough in CR's eyes to consider starting him against his favorite player.
(As we have seen it was never the case after DC very impressive performances... the intention of CR was clear from the beginning!)
Such a thing would only happen if Criscito or Dc would have the chances Marchisio and Giovinco had when Zanetti, Tiago, Poulsen and Neddy were not available and they have managed to outperform the starter with a couple of consecutive exceptional performances!
I can be certain that as long as we have CR, Criscito has def no chance to overthrow Molinaro from his place, regardless of their performances.
Even worse, i am also afraid that he also have limited chances to replace Legro too, despite not being as hard as replacing CR's son...
