Of course, this season Juventus is the most favored to get the Scudetto trophy this season, because as you said, Juventus doesn't have a big schedule so the players' fitness and concentration don't decrease. This is very different from other Scudetto competitors who have very busy schedules, of course their stamina will be drained and players will even easily suffer injuries which will make them unable to compete for the Scudetto trophy.
So in essence, if asked who has the most potential to win the Scudetto this season, the answer is of course Juventus, but with the condition that you must not underestimate any opponent, and Allegri must be able to use all his organizational abilities. strategy in each match so that you can remain consistent.
In the long run, yes, Juventus, having no cups to play, is favored from a physical fitness point of view compared to other teams who have grueling shifts that put the players bodies to the test.
But this is not enough, look at Inter, clearly we will see towards the end of the championship how it is going.
