Our defensive record has more to do with the fact that we have 3 CBs and 2 wingbacks and 3 CMs to support them, also one of the worlds greatest keepers, rather than Bonucci's individual defensive skills...
Bonucci is favored from all that, exactly as Guardiola is favored when he only had to coach the strongest and wealthiest teams/players in the world. Thats the perfect receipe of overhyping and overrating someone.
And as for Cannavaro, he was trully one of the world's best CBs, but many of our gay fans who like Bonucci more because of his looks, rather than his defending will not hesitate to compare them.
My golden standard is Iuliano, he was never great like Ferrara, or even Montero, let alone Thuram and Cannavaro, but he was no stranger to tacklings or man markings. Chiellini and Barzagli at this age are more capable defenders, but when you have to face a Lewa at Bayern and the game has to be decided by a one on one chance of our CB with him, would you pick Bonucci, or Iuliano to stop him???
Thaaats the golden standard right there, whoever fails the Iuliano test is not a Juve material CB in my books...
Maldini , Cafu ,Lizarazu, Zambro and Thuram were venerated for their offensive contributions, but they were also extremely capable at defending.The offensive play was just the extra that made the difference, not the only reason they were rated.
Bonucci is only praised for his passes and long balls, but never for his defensive work, when was the last time you remember him of depossessing anyone?? How many times this happens per season!
