Their defense isn't as good as it has been in the past, and their Hypesman Trophy candidate QB isn't that good either.

When you go from having the #1 QB pick on your team to having a QB that might not get picked up in the transfer portal, you tend to fall off a bit.

Ohio State broke them last year. They really broke them the year before but the refs decided to help them out a bit. 

In all seriousness, I think it is the combination that Dabo is a good not great coach and their offense hasn't developed. They don't have Watson or TL to fall back on. Maybe other teams have figured out how to hide their offensive signals a little bit better as well.
