Both teams have played against atrocious schedules.  One has played slightly worse opponents, but the other has played 2 lower division opponents.  Neither has played a ranked opponent.

One has a higher powered offense, while the other has a slightly better defense.  Both teams have one close win (6 points), but all of their other games were blowouts.

So...

Any idea why one team is ranked in the top 6 in the coaches' poll, while the other barely cracks the top 25?  Any idea why one team got 4 times as many points in the AP poll as the other?

What is it about Texas Tech (Team A) that is that much more impressive than Tulsa (Team B)?

Just askin'.
