A 14-point lead at halftime. A 21-point lead early in the third quarter.
The Ravens' offense didn't score a single point in the second half, and the Baltimore defense allowed two drives of at least 95 yards in the fourth quarter, and all of a sudden, we've got a 28-28 tie at the end of regulation.
Texans quarterback Matt Schaub led Houston back from a deep hole, the Texans put up 301 yards in the second half, and trailing by eight with under three minutes left, they got an Andre Johnson touchdown reception and a Jacoby Jones two-point conversion to tie the game up.
The Baltimore defense gave up 15 fourth quarter points, but the offense didn't do much either.
And now, again, we're inexplicably heading to overtime.
