You're wrong.
I decided to rewatch the 4th quarter and, actually, Stroud played great! You may not be aware, but Marvin Harrison ws knocked out of the game at nearly the 3nd of the 3rd quarter on an ILLEGAL hit that was called targeting on the field but was then overruled by the blind (or dishonest) replay official. Ohio State's good tight-end was knocked out of the game in the first half. Ohio State was also playing with their 3rd and 4th string running backs. And, not to mention, Jaxon Smith-Njigba was also OUT of the game.
Here is a breakdown that I put together of Ohio State's 4th quarter offensive numbers.
1st possession:
1st RB 2-yard rush
2nd Stroud incomplete pass
Stroud under pressure rushes for 6 yards.
Punt
2nd possession
1st 9 yard pass completion
2nd rush for 12 yards
1st Stroud rolls right and rushes for 4 yards
Stroud drops back, is pressured, and runs for 18 yards
1st RB runs for 1 yard
2nd screen pass completed for no gain
3rd Stroud completes pass for 10 yard gain and a 1st down
1st Stroud designed run for 5 yards
2nd Stroud sacked for 12 yard loss
3rd Stroud incomplete pass
4th Field Goal from 46 yards
3rd Possession
1st Stroud drops back, scrambles for 5 yards
2nd Stroud pass completed 14 yard gain & first down
1st Stroud drops back and then scrambles for 29-yard-gain to Georgia 30. 24 seconds remain in game, Ohio State down 1, 2 remaining timeouts.
1st OSU rush for 1-yard loss
2nd Incomplete (dropped) pass
3rd Stroud under pressure on 3rd and 11 scambles and throws ball out of bounds.
4th 8 seconds remaining, Ohio State kicker badly misses 50 yard FG try
Game over
If the usually reliable kicker had made that field goal, Stroud would likely have a national championship ring and then you'd be happy to have him, right?
