Robert Windsor came up through the ranks the old fashioned way. He redshirted in 2015, then got an Big Ten All-Freshman Team Honorable mention by BTN.com. By his redshirt sophomore season, he was playing in every game, and, in 2018, he was a full-time starter.
Windsor was named to an All-Big Ten team by either the coaches or the media in his final two seasons (2018, 2019), helping Penn State reach the Citrus Bowl in 2018, then the Cotton Bowl in 2019.
Windsor had 119 tackles in his career, 49 of which solo.
