So are the very good teams. The best of teams may only be favored to win 60% of the time. Most series are 55%/45%.
That said, I do think they had enough talent to win it all in 2021, but the failures of Vlad, Kirk, Varsho, Manoah, Berrios (2022), even Springer has made it feel like they aren't good enough. Not sure how much of that blame I can put on Atkins. Some yes, but there's some horrible luck involved there.
Blah - I'm done with this convo. Sorry.
