It is.
I can't say anything about Conte as a coach. Maybe he does have quality. He might be better than, say, Allegri who just won the scudetto. But even Allegri (if he was still a Cagliari coach now) would have been a bad choice for this Juve because a coach can not do a miracle with a bad team. What we needed was a coach with success behind him and lots of authority. Someone who was gonna literally order Marotta to buy this and that player, not someone who was just gonna say that he plays 4-4-2 and wait for Marotta to buy him some players.
Also, a coach who already coached big teams and great players, a coach that had a success recently, knows which players he needs to be successful with Juve. He'll know exactly which realistic targets to bring to Juve. What can Conte possibly do in this regard? Can he be the reason why some player would choose Juve over Bayern?
