The Indiana sophomore quarterback said he didn't want to take anything away from the Spartans but a lot of IU's troubles Saturday were self-inflicted.
"Don't get me wrong they're a great defense but we stopped ourselves more than they stopped us, I think,'' Sudfeld said. "I just felt like I was a hair off on four or five deep balls. We just weren't in sync like we have to be against such a good defense.
By his own standards this season, Sudfeld's numbers were off significantly. He completed 14-of-30 passes for 137 yards with no touchdowns and two sacks. He would eventually give way to Tre Roberson who completed 11-of-17 passes for 122 yards and a pair of touchdowns.
Coming into the game Sudfeld had been averaging 293.4 yards per game. He had 13 touchdown passes in the first five games.
Saturday, Sudfeld was just off target. He overthrew a couple of receivers on passes he normally would make. One time he was scrambling to his left and didn't get his feet set and Duwyce Wilson was lunging to his right when the pass was delivered to his left. He just lacked the consistency that had made him one of the best quarterbacks in the Big Ten in the early going this season.
"It was just us,'' Sudfeld said. "We were just a hair off on some deep balls that is usually our bread and butter. Me to Cody, me to Kofi, I was just a hair off and overthrew them. Again I was just a hair off. We'll get that fixed. It's good to know there are a lot of things we can improve on.
"We really can play so much better than we did.''
Sudfeld's final series of the game was the first of the fourth quarter. He threw an incompletion on first down on a play where it looked like he had an equipment problem. He was limping around and adjusting a knee brace on his left leg. Two more incompletions later, Sudfeld and the Hoosiers were off the field quickly in a three-and-out. Sudfeld wouldn't return.
Kevin Wilson didn't recall Sudfeld getting hurt so he couldn't answer a question about the status of his sophomore quarterback. But Sudfeld explained it as pieces of dirt getting underneath his brace and causing him some discomfort. Sudfeld said he's fine and will be ready to go against Michigan.
So what exactly were the problems the Michigan State defense was posing on Saturday?
"They have really good corners that make you fight for every reception,'' Sudfeld said. "But a few times I was just over shooting them a little bit. They're really good at press coverage though. Give them credit. But we need to convert on those.''
Sudfeld was asked if the lack of an IU running game make it more difficult to be successful against the Michigan State defense. IU ran for 92 yards on 27 carries.
Again, I missed throws that were there, just some deep throws,'' Sudfeld said. "I don't think the run game affected us very much. We were just a hair off and when you pass as much as we do at times you just can't afford to be off like that. It's frustrating but at the same time we're looking forward to this week and this challenge.''
