Not ready to throw him in the hall of fame just yet. But the point of the OP topic for game 1.....
During the 1st half Luke brought the juice. You could see his energy and play making ability permeate the team. 27-6 at halftime against Penn State. And overall I thought he played pretty well, although the play calling and pace took a serious slow nose dive in the 2nd half.
Again, it's his first shot as QB1. Not too shabby.
And you know he was nervous, even though it wasn't really brought up.
I also thought Adrian Martinez played real well his first start too, against Colorado years ago. The sky was the limit. It was exciting. But he got hurt in the second half of that game as we know, but it was encouraging play from his 1st start as well.
I don't see a huge difference after one game so far, but I do see an important one. Winners in charge usually end up on the winning side of things. No matter who helps getting it done. QB1 heads the team towards victory, and they all feed off of him and do their thing to get it done together. Even if QB1 struggles at times. And that's something you can't teach because it's infectious.
So I would say, overall, a nice win, a good start, and optimism for growth.
