That is not the point. You are using the gift of hindsight here.
What I am saying, is that in the summer of 2011 before Conte got hired, if Conte and Allegri were both available, and given both coaches CV at that time, it would have been incredibly difficult to justify hiring Conte over Allegri back then.
Would you have rather had a coach whose claim to fame was getting two clubs to Serie A and quitting on a club in the middle of a season, or a coach who the year previous had been named coach of the year at Cagliari, and had just won a scudetto?
What they did after that is irrelevant, because we are talking about that particular moment in time
