Even so, the committee got it right. tOSU, even though they lost earlier to PSU, is the obviously better team. And PSU has no valid claim above any of the other 3. For personal petty reasons, I would have loved to see Ohio State left out but that really has nothing to do with anything.
Personally, I would put PSU in over UW based off resume. But both are conference champions so leaving either out is unfair when tOSU gets in without winning a division.
That said they are definitely the 2nd best team in the country, even if they are ranked 3rd.
