Missouri entered today's game giving up points on just 14 of 25 possessions by opponents, the nation's No. 2 mark at 56 percent, behind only Boise State.
The Tigers defense got -- or was given -- another big stop with just seconds left in the first half, leaving them with a 21-14 halftime lead.
Carson Coffman spent the drive slicing up the Missouri secondary for 48 yards, completing his last three passes on the drive after coming back in off the bench to run the two-minute drill in place of the running-inclined Collin Klein.
But on the goal line, Coffman fumbled the snap and Missouri's Jacquies Smith recovered it. Missouri's defense has been stout all season when backed deep into its own territory, but to have a defensive red-zone percentage as low as the Tigers do, it takes a little luck once in awhile.
For Missouri, Coffman's fumble -- lucky or not -- is a welcome end to a quarter that saw the defense otherwise struggle.
