EAST LANSING — Mark Dantonio made it loud and clear. He is not pleased with Michigan State’s offense, either. “I can say this — football is a game of effort, toughness and knowing what to do,” Dantonio said during his weekly news conference Tuesday, echoing four days of frustration from his fan base. “Half of our team figured that out, half of it didn’t. We will make sure that other half gets figured out this week. So that’s my message to our football team.” A glowing performance Friday night by the Spartans’ defense in a 28-7 win over Tulsa, in which they set a school record with minus-73 rushing yards allowed and 80 total yards, got overshadowed by a disappointing debut for a revamped offense under new coordinator Brad Salem. MSU ran for just 108 yards and had 303 total yards, both below the 2018 season averages of 124.8 yards rushing and 342.1 yards of total offense, lowest of the Dantonio era. The Spartans got just 68 yards on 30 carries from running backs Connor Heyward, La’Darius Jefferson and Elijah Collins, behind an offensive line that failed to generate consistent holes and push up front. “Not good enough,” Dantonio said of the rushing totals. “We got to get on the right people. As I just said, you got to know where to go, you got to play with effort and toughness. Too much of that to me was lacking. “I'm going to call it as I see it up here right now. Going to send a message to our football team. We have a long season ahead of us. We can play much better than that. … That message is going to get set, whether it's public or not. I'm sure nobody appreciates us running the ball for 67 yards, especially the guy in charge. We'll fix that.” Those problems, Dantonio said, remain all-inclusive — from wide receivers not running full-speed routes to offensive linemen being lax at the point of attack to penalties pushing MSU backward at the start of drives. Beyond lack of execution from players, Dantonio pointed to himself and his staff for the struggles on offense. However, he emphasized that he is not panicking after one game. “This is a result-oriented business, I understand that,” he said. “We have to make sure that we're pushing forward in that endeavor. I got to send a message, OK? Sometimes I get a little irritable before I walk into these press conferences. I take it with me. Sometimes I get irritable walking out, OK? Take that with me, too. “We're going to get it right.” Dantonio said senior long snapper Ryan Armour will miss the rest of the season and need surgery after suffering a left leg injury in Friday’s fourth quarter. That means true freshman Jude Pedrozo will take over snapping duties on punts and place-kicks. The 6-foot-1, 224-pound Pedrozo, from Westerville, Ohio, snapped on MSU’s final punt against Tulsa. He was considered a five-star long snapping prospect, according to Rubio Long Snapping. “He was the heir apparent,” Dantonio said of Pedrozo. “He's a good snapper. We recruited him with that idea, that he would be the guy. He's just going to have to pick up the slack a little earlier.” Dantonio said senior offensive lineman Cole Chewins remains out of action and “needs to practice full-go before he can play.” Dantonio did not give an update on the ankle injury suffered by A.J. Arcuri, who was supposed to take over at left tackle for Chewins. That required fellow junior Kevin Jarvis to flip from right guard to the left edge about 10 days before the opener. True freshman Anthony Williams also remains “nicked up,” and Dantonio said it depends on how his week goes if he will make his debut vs. Western Michigan on Saturday (7:30 p.m., BTN). The 13th-year coach also said second-string defensive end Jack Camper is expected back soon after missing the opener Friday. Defense an elixir: “I think our defense played outstanding. A lot of takeaways, very difficult to run the ball on, very difficult to pass the ball on, really covered all the bases. We had nine three-and-outs, seven sacks, took the ball away from them three times, blocked a punt, safety in addition to that, scored a touchdown. All you could ask for.” On 14 penalties for 122 yards: “You have the good, the bad and the ugly — the ugly was the penalties. We talk about penalties over and over and over again. Some of them are forced penalties, a (pass interference) or something like that. Sometimes a holding call. Some of them are unforced. We have to limit the unforced penalties, jumping off-sides. We had too many of those that put us immediately in situations.” On the offensive fixes that need to be made: “Football is a game of repetition, like I keep saying. You're not going to just say, 'Hey, let's run that play, nobody else has ever run that play before.' I don't think that exists in this sport. If you believe that, people are a little bit naive. “As I said earlier, this is about hard work and execution in terms of you got to — I'm holding our coaches accountable as well in this. It's about play selection and play call. We need to do a better job in that as well. I'm not shying away from that responsibility. But at the end of the day, there’s so many ways to skin a cat. At the end of the day, you better skin the cat. There's another good Quote: for you. You write that down.” On his first chance to tie Duffy Daugherty’s MSU total wins record of 109: “I'm trying to get better. I've said that, I've talked about that before. I believe that's something that a lot of people have worked to do. When we get there, we'll get there.” On WMU players being out to prove something to a Big Ten opponent: “I think our guys will have motivation this week. What do you think? We'll be motivated. (The Broncos) are going to come and play hard, they always have. They always have. I got a great deal of respect for a Mid-American Conference, in particular Western Michigan, what they've been able to accomplish.” Contact Chris Solari at csolari@freepress.com .
