We didn't make adjustments.  Oregon let off the gas and stopped running what was working in the 1st half.  Oregon was still gashing us for big plays in the second half and a lot of times their drives ended due to their own mistakes.
		
		
	 
Yes Oregon ran the ball more in the 2nd half but their RB is a beast. If Diaco and our D didn't improve or adjust, they'd have scored 70 on us just by running. Defense did a great job in the 2nd half containing him and the run game. And yes, when they did throw our secondary was in much better position then they were in the first. 
You may see it as Ducks "taking a conservative approach" but you could also see that the D played much better. Do you believe Ducks didn't want to score in the 2nd half? And to say the Ducks stopped themselves some is probably true but our offense did the same all day. And trust me, the D made plays in the 2nd. Not everything was handed to them. Not all of those were due to Ducks "giving it to us" Also their offense was ridiculously lucky in the first. But opportunity is needed for luck and the shirts took away that opportunity in the 2nd. 
When the game ended, I had no doubt our defense was much better than theirs. When the game ended I saw this team will be unbelievably better at the end of the season. The team, especially the D, never gave up and if you don't see that as an improvement to what's been here over the last 5 years, then your just a sad person and I can't help you.
