^^^ RTW has it right. He has them taking a TO after first down which they did. Pennington taking a knee & TO #2 in RTW scenario would have been the play Ronnie scored on.
Actually, he is wrong
at least according the NFL.coms play by play:
1:57 R. Brown left end for six yards
Timeout #1 by Houston
Ronnie scored the next play. If he had fallen to the ground at the one, Houston would have to take their second timeout.
We would have had first down at the 1 or 2 with Houston having one TO left.
Kneel (Hou Calls final TO)
We have two plays with which we can kneel and Houston cannot stop the clock. That's at at least 1:20 we can kill right there.
Houston would have had less than 25 seconds (and this is being generous) to get in FG range with no TOs
