I rather briefly watched some you tube videos last night of folks predicting this and that. Suffice it to say they mostly disagreed, which is fine. If enough "experts" predict outcomes, one or a few will be right and hailed as maestros of CFB, for a year.
As noted separately, the 12 teams this year (and more) all seem "quirky", capable of looking great one week and awful the next, losing to "NIU" and the like. Ohio State has looked solid when played teams not having an "Mic" in their name. UGA looks pretty good when playing Texas but not so much Kentucky and Tech, not to mention Ole Miss and a half against Bama.
What to do? It's close to a crap shoot. We could have four upsets this weekend, not likely, but I'd guess at least one will occur. Then the experts will all tell us how Notre Dame didn't play anybody, their best win was "X", and Indiana exposed them. Or he Vols were battle tested in the SEC and Ohio State was exposed. Or how Penn State lost their backup QB. One "expert" picked Clemson over Texas. Why do we listen to these experts? It reminds me of the stock prognosticators who often get paid Big Bucks to disagree. If any of them really knew, they'd be investing, not yacking.
Historically, a 7 point dog will win about 1 time in 3, and we have 3 games in that range.
