It might very well be the worst squad since Delneri times (if not its really close), but not only RUSs point is not an absolute nonsense as you claim, its pretty clear to see for most that even with this squad Juventus should be fighting for Scudetto.
Milan, Napoli and Inter have been in the Scudetto race all season, all of them still are and obviously neither Napoli nor Milan have better teams than Juventus (tbh I dont like or rate Inter much either, but at least they have more than a handful high quality players) and none of those teams are on some blistering pace thats impossible to match. Yet at no point in the season we truly entered the Scudetto race, a couple of times we were a few positive results away from that and it never materialized.
Obviously this season isnt a success, Top4 isnt an achievement with this team, its bare minimum. Id give Max continuity and fix at least some problems with the squad, God knows theres room for improvement, but its possible to not ask for Allegri's head and still admit he couldve done better.
