I'm guessing we just aren't as good as we anticipated (hoped).
Reality is that this is a team that was LAST in the Big 12 and I think a lot of us incorrectly assumed that (historically) the Big 10 was not going to be much of a challenge.
And maybe it wouldn't have been with our older teams, but this team is not them.
For whatever reason, they are missing something (including a bunch of mental errors) that should not be occurring this late in the season.
I am not down on the players or coaches and I think better days are ahead, but the results tell me we thought we were better than we have shown.
