Unexpected teams getting unexpected results on early weeks may not be indicating their whole season. Some teams get some good results on a few weeks results, but then could become bad, and on contrary some good teams could have bad results on early weeks and then become much better later on as well. For example I believe that Juventus will finish very well this season, I think they have a chance to be the winner or second place, and Inter looks like the other team that will either win or be second place.
Milan looks bad and everyone says they are much worse, but I think they will recover. On the same logic, Udinese and Torino will not do that great, they had a decent start but they will not end up that top at all.
The crapshoot of early seasons is unique. Teams are rusty; fresh recruits are settling in; strategies are still under development. It is far too early to name someone or discount someone. Juventus is what? They seem to be a wounded lion. Though injuries were rampant last season, they nevertheless worked their way to a solid finish. Masters of the mid-season reversal are they. Look out when they start to move. Milan,? Sleeping on them is not advised. Though they start slowly, they have that Pioli magic. When it counts, they will be there. Remember, this is Serie A, not some Mickey Mouse league. Every team can defeat every other team on any one day
