That's because you don't understand Bonucci's role in the team in our 3-5-2. In a back four I'd agree with you, but defending is not the important thing, it is only half of the importance of Bonucci's role. He's not a real central defender, which is just as well, considering he's not being asked to play that role.
Glad that we agree that he is not a real CB, or a defender for the same matter!!
Now, as of his role, yes, i agree that he is mostly used for his passing, to be the last man in the defense our players can return the ball and then distribute it to one available player.
This is indeed an important role, that Barza nd Chie are not particularly good at because of their poor passing, BUT, still that doesnt excuse his defensive inefficiences!!
We are not Bari, we are Juventus, we aspire to become a competitive team again, when cannot afford players who can do nothing but pass the ball around.
Because at the highest level, the opposition has quality players and will exploit any weakness we show.
Even if Bonucci's main role is to pass the ball around, inevitably, time will come that he will also have to defend, esp as long as he sits in the heart of our defense.
MAybe at most of the Serie A agmes, he doesnt, but in Chie'a absence, or in tight matches, it is mandatory.
Even versus mediocre teams, once or twice per game, the need arises and Bonucci messes up, almost every single time.
We can be better and dominate the game, but we cannot always dominate it enough not to allow one single opportunity for them.
The better the opposition happen to be, the more chances they get, the more chances they get, the more possible it becomes to exploit our weakness.
In these situations, Bonucci's presence in the heart of our defense becomes our deepest flaw.
Unfortunately, by now most of the teams and players know it and are actively trying to exploit at any given.
This has been proven time and time again and we ought to find a way to fix it!
I am not expecting from Bonucci to become a Nesta and start teaching Barza and Chie how to mark/tackle/diposses/clear the ball.
He will never reach that level, obviously he was far too limited for that, that was obvious from the very day we were investing that immense ammount of cash and players on him.
But the least i was expecting from him, was to learn how to be more efficient at closing doing those holes when the moment demands it!
Just like Caceres did in the last match. Holding one of the CBs slots, he ought to offer at least that much of a comfort.
There are games and moments, that being able to defend and stop the man, becomes of extreme importance.
Heck even Pirlo, does it when it is absolutely needed. Bonucci is just unable to do it, even if his life depends on it.
I am not asking him to change his role, yet simply to improve his defending enough to help us survive those moments.
I sincerely thought that in time, he will improve, it is inevitable for anyone. Even Legro, a far more limited defender became decent enough at the perfect age for the CB, 28-32.
However Bonucci shows evidence that he is not going to improve, he is as raw, (at defending) as the very first years he joined us.
He has the confidence, that the starters place is guaranteed, no matter hsi inefficiencies and occassional mistakes that lead to conceding/point loses/disqualifications.
He was given far too much confidence for all the wrong reasons. There is no ambition to improve, he doesnt even realise that he is holding us back.
We should be more vocal to his criticism, maybe that way he will understand it and do smth about it!
After the super ownage, we had conceded by investing a fortune and Criscito on him, all the while trying to keep as many NT cappers, as we could for the nationalistic ItalJuve project,
we had no choice but to keep and hope that someday he will improve.
A big team like Juventus cannot afford a time bomb in the heart of her defense, if we want to compete at the highest level, though.
We must demand for him to improve, or be replaced by a better a player! And if there is not an Italian good enough for the task, then so be it, lets get a foreigner!
Normally Bonucci should be loaned out some years ago, after being so costly in games and points, up untill last year and then subbed, up untill he reaches the desirable level.
Just like we did with Legro.
Our needs demanded a different strategy back then and we had to accept heavy compromises, but we are not in that desperate position anymore, we really deserve better now!
