There was a time not long ago that maybe a handful of true freshmen would come in and play right away at Michigan State. In 2007, head coach Mark Dantonio’s first season, the Spartans played six true freshmen. That was the most MSU would play until 2015, when it was again six freshmen who saw the field. The 2016 season was an entirely different story, with Michigan State playing nine true freshmen because of a combination of performance and injuries. Under normal circumstances, that could be considered an aberration and MSU could go back to redshirting the vast majority of its 2017 class.
