Blake Horvath and the Navy offense weren't scared of Memphis' defense.

And the proof was in the Midshipmen's play Saturday, when the quarterback scored six touchdowns and helped Navy pull off a 56-44 upset over the Tigers (3-1, 0-1 American Athletic Conference) at Navy-Marine Corps Memorial Stadium.

Memphis' defense looked lost for almost the entire afternoon, and after leading the Tigers to a massive non-conference win over Florida State a week ago, had no answers for coordinator Drew Cronic's new-look Navy offense.

Memphis entered the game ranked No. 23 in the US LBM Coaches Poll and in what appeared to be pole position for a College Football Playoff spot. But that may have all gone out the window with the loss. The Tigers almost certainly will need to win the rest of their games just to have a shot at the AAC title game, and even then, the playoff won't be a guarantee.

Here are our overreactions from the game.

Memphis' College Football Playoff run is over

Remember, we're talking overreactions here.

There was plenty of offseason talk about how Memphis was the favorite to earn the Group of Five's spot in the College Football Playoff. That talk only got louder after the Tigers dispatched Florida State in Tallahassee last weekend, and it's why Memphis was a significant favorite over Navy.

Now, though? It's going to depend on how Navy plays the rest of the season. The Midshipmen were outstanding on Saturday, and if they continue to play like that, this loss won't look so bad. If they don't? This loss could sink Memphis' résumé at the end of the season.

The Tigers' defense has serious flaws

This would've been unfathomable to say a few hours ago, when Memphis was riding high off the win at Florida State and coordinator Jordon Hankins' defense had just spent a week earning national praise for its performance. But the Navy offense had zero problems attacking that same unit, and the Tigers spent Saturday afternoon looking confused and without answers to deal with Navy's unique offensive attack.

Memphis won't face another offense like this one, so there's reason to think this could be a one-off. But tackling will be an emphasis moving forward. And the secondary will have to bounce back from a game where Midshipmen receivers were constantly behind them to reel off long plays.

Blake Horvath is a Heisman candidate, and the Midshipmen could win the AAC

Navy wasn't on anyone's preseason list of potential AAC champions. The Midshipmen were picked to finish 11th in the preseason media poll, but they just knocked off the team picked by almost everyone to win the conference.

There's still plenty of football to be played, of course. But Saturday's performance means the Midshipmen could be legitimate threats to win the AAC.

That's largely because of the performance of Horvath, who was outstanding throughout the game with almost everything he did. Horvath was 9 of 12 for 192 yards and two touchdowns passing, and he added 12 carries for 211 yards and four touchdowns rushing. If he plays like that every game, he'll be taking a trip to New York City in December.
