Let's not act like Will Howard was a world beater coming into the season either. The dude was a 54% career passer with 9 TD and 11 INT coming into the season. I assume they were enamored with Martinez ability to run the ball and liked that element that he brought and him coming in would allow KSU to play Howard in the max 4 games and redshirt him.
I am asking this as a serious question as I didn't watch the game, but what did Adrian do that made the loss almost all of his fault? I looked at the stats and he was 21/31 passing with 1 TD and 0 INT, 12 carries for 59 yards and 0 TD. It doesn't show that he turned the ball over, but looked like he may have checked down a lot as 21 completions and only throwing for 150 yards seems like it is underwhelming. I did watch a bit of some other games early and it did seem like he played pretty tentatively in his first few games.
The thing about Adrian was, when he was at Nebraska, you could look at his stat line and think he had a great game. 25/35 for 310 yards passing with 3 TD/1 INT, 100 yards rushing with 1 TD. Looking at that you would think, wow, what a game. But, digging further into it, that one interception came with the team up 3 points with 6 minutes left to play at our own 20 yard line to set up the winning score for the other team. Then a fumble on the final drive with a chance to win it. You could just never count on him when the chips were down and it was time to win the game.
I loved the kid as he was a great person, but just couldn't be counted on to win the big one. When NU had a chance at Burrow, I said at the time that NU needed to take him if he would come here as we really didn't know what we had at QB. We had Martinez who was a true freshman that was coming off of a bad HS shoulder injury, unproven Tristan Gebbia, transfer Noah Vedral and a walk on in Andrew Bunch. Frost making the "is he better than what we've got" statement is a microcosm of his time at NU. He just couldn't get out of his own way.
