Hey, let’s just jog your recent memory:

Last weekend the likes of then-No. 1 Alabama, then-No. 4 Penn State and then-No. 10 BYU all went down to defeat.

Okay, so Penn State was “expected” to lose at 2.5-point Iowa but the other guys were – to put it mildly – quite stunned by their results.

Now, the $64,000 question as we turn our gridiron attention to this Saturday’s jam-packed College Football card is what unbeaten teams truly need to be worried about being on “upset alert” here.

Ahh, we’ll be glad to tell you the truth and nothing but the truth in just a moment but consider that there are a grand total of 13 teams that are still undefeated SU (straight-up) as we head towards this mid-October weekend — and they are …

Cincinnati, Coastal Carolina, Georgia, Iowa, Kentucky, Michigan, Michigan State, Oklahoma, Oklahoma State, San Diego State, SMU, UTSA and Wake Forest all remain perfecto SU but which ones could be busted in this here-and-now weekend?

Here’s some overall thoughts:

The Las Vegas price tag for the Big Ten bash between Michigan State (6-0) at short-handed Indiana has risen from Sparty minus a field goal to minus 4.5 points but may we remind y’all that Michigan State’s attempting to win/cover back-to-back road games (see last weekend’s 31-13 triumph at 4-point pup Rutgers) and that’s never an easy chore.

In fact, the last time that the Spartans won and covered back-to-back road games was in 2013. Quickie fact on the IU Hoosiers who continue to play without QB Michael Penix, Jr. (who did toss 7 INTs in parts of five games this season): Indiana’s off a bye week and comes in having lost three in a row to Mr. Vig.

Oklahoma (6-0) may take home this week’s “paranoia award” as fifth-year head coach Lincoln Riley is stewing over the fact that a couple of OU students “spotted” kid QB Caleb Williams taking the majority of snaps this week in preparation for Saturday’s high-noon Eastern time clash versus double-digit dog TCU.

Williams – who came off the pine last week to engineer the great 55-48 come-from-behind win/cover against archrival Texas by throwing for 211 yards and two TDs and rushing for 88 yards and another score – is indeed the “future” for the Sooners at the position as one-time Heisman Trophy frontrunner Spencer Rattler’s been put on ice (save for his successful two-point conversion pass against the ‘Horns) and one thing for sure is the betting public approves the switch at QBs as Oklahoma jumped from an 11.5-point fav to a 13.5-point favorite in the course of the past 48 hours.

Meanwhile, did you know the underdog Horned Frogs have covered seven of their last 11 conference games dating back to the start of last season?

That’s right, we’ll be paying extra-special attention to Michigan State at Indiana, TCU at Oklahoma here.

And one other item on the menu board here when it comes to this weekend’s College Football activity:

Lots of talk about schedules these days. For example, #2 Iowa (6-0 SU / 5-1 ATS) already has disposed of then-top 10 teams such as Iowa State and Penn State – hats off to the ‘Eyes there – but did you realize that Iowa does not play Ohio State, Michigan or Michigan State? For sure, Kirk Ferentz’s team will be betting favorites in its remaining six regular-season affairs while it’s worth noting Michigan (also 6-0 SU / 5-1) still has games remaining at Michigan State, at Penn State and home to Ohio State. Hey, if the maize-and-blue gets thru that sked then Jim Harbaugh’s crew could be #1 everywhere.

One team that could be a tad overrated based on beating up some bad teams is Wake Forest: The Demon Deacons (6-0 SU / 2-3-1 ATS) own ACC wins against Florida State, Virginia, Louisville and Syracuse but truth be told there’s a chance none of those four foes (or three of em, at least) won’t even make it to the holiday bowl season.

The NFL Week 6 menu revved up with Thursday Night’s Tampa Bay 28-22 non-cover win at 7-point dog Philadelphia (two more TD chucks by Tom Brady) but as long as we’re talkin’ unbeaten teams, well, the NFL’s only got one of ‘em while heading into Sunday’s sked:

The Arizona Cardinals are 5-0 SU and they’re a tasty 4-1 ATS (against the spread) but get a load of this:

The Redbirds – who are currently listed as a 3-point underdog in Cleveland – rank a lowly 28th league-wide in rushing defense (allowing 139 ground yards per game) and that’s dicey when going up against the Browns’ one-two punch of RBs Nick Chubb and Kareem Hunt, both of whom should play despite the injury list status.

Note Arizona QB Kyler Murray (shoulder) and do-it-all WR DeAndre Hopkins (possibly Covid) are not exactly at full-strength for the Cards.

Maybe those 1972 Miami Dolphins will be popping the champagne corks come late Sunday afternoon … stay tuned.

Here’s a couple of spread-related ditties of interest heading into NFL Week 6 …

The Dallas Cowboys are the only team with a perfect pointspread mark at 5-0 thus far and just remember that last year’s ‘Boys started off that season with an eight-game ATS losing streak.

There aren’t any NFL squads that are winless versus the vig but both the Las Vegas Raiders – perhaps you’ve heard about them this week! –and the San Francisco 49ers enter Sunday’s action with NFL-worst three-game spread losing streaks. Might want to know that the Niners now are a collective 33-38-1 against the odds under fifth-year head coach Kyle Shanahan. Sure, injuries sapped last year’s squad that still finished 7-9 ATS but overall we’re not detecting “genius” from these numbers.
