Put the 2 offenses side by side and neither looks good. Oklahoma has scored 10, 14, 13, 27 and 13 over its last 5. The Sooners have topped 14 points once in that stretch, and that was the 27-24 win over Texas, which was No. 1 at the time. Their defense is what has kept them in games. Outside a 41-13 loss at Georgia, nobody in that run scored more than 24 on them.
Mississippi State's season split in half. The Bulldogs opened 3-0 in this window with 38 at Minnesota, 41 at South Carolina and 31 against Missouri. Then they lost 56-23 to Alabama at home and 31-0 at LSU, each by more than 30. The LSU game wasn't a total collapse. Puckett got the Bulldogs inside the LSU 40 five times and all 5 drives ended on failed fourth downs, one of them from the Tigers' 6. That's an offense that moves the ball and then can't finish, and a healthier depth chart would help it finish.
For Oklahoma, the issue is finishing games. The Sooners went into the fourth quarter with the lead against Kentucky, gave up 14 straight points and didn't score again. A defense this solid deserves more than 13 points. If Mateer protects the ball late, Oklahoma's floor is a lot higher than 3-3 suggests.
Mississippi State is 4-2 and home after 2 ugly losses. Oklahoma is 3-3 and on the road after giving one away. Both teams are 1 loss away from their season going sideways. The answer to how this goes is probably on Mississippi State's injury report: if Taylor and Bothwell play, this is a real game, and if they don't, Oklahoma's defense is facing what LSU just shut out.
