Well I actually don't think the defender's in this Napoli team is that horrible, it's just boils down to adapting to the playing pattern of Antonio conte, which they are really finding it difficult to graps, ok let's look at the kind of performance that Napoli put in against Verona, do you think this Napoli team is that average to perform so poorly like that?
Though they are actually missing the presence of their star attacker in victor osimhen but his presence wouldn't change and solve all the problems in this Napoli team, so I believe that they will surely improve as the season goes by if they can continue to work in the right direction.
There are still many opportunities and indeed the need for adaptation from several lines, and also Conte still needs the same rights with the scheme that will be used considering the defeat against Verona created so much homework for Napoli and Conte, so this early match can still be understood with the 3-0 defeat from Verona is indeed painful but at least in the next match Conte's team can steal points when hosting Bologna next week.
