With virtually any coaching change comes roster turnover.

When a coach departs or is fired, a team made up largely of players recruited by the coach and his staff is left to decide whether it wants to remain at a school and with a program after such sudden change.

It’s something Michigan State football is experiencing now.

One day after the Spartans’ tumultuous 2023 season ended with a 42-0 loss to Penn State, the university announced it had hired Jonathan Smith away from Oregon State. Smith replaces Mel Tucker, who was fired in late September for cause amid a university investigation into alleged sexual misconduct.

Smith is a well-regarded coach who rebuilt Oregon State, his alma mater, into one of the Pac-12’s best programs over the past two seasons, but his arrival and the change it will bring – a new head coach, a new coaching staff, a new system and scheme – creates uncertainty for players, who may hope to continue their college careers elsewhere. With NCAA athletes now able to transfer once during their careers without the penalty of having to sit out a year, that movement becomes much more common.

In the days after the season finale and Smith’s hiring, dozens of Spartans players have announced they have entered the transfer portal, though a handful have since withdrawn their names and plan to stay at MSU.

Here’s a rundown of who is leaving and staying:

Note: Players have from Dec. 4 to Jan. 2, 2024 to enter their name in the portal during the NCAA’s fall window.

Snow – whose father, Eric, was a guard at Michigan State and later in the NBA – saw his past two years with the Spartans ravaged by injuries.

He missed the 2022 season after suffering a leg injury in the opener against Western Michigan and was limited to four games this season, missing the final six contests with an unspecified ailment. During those four games, he played 55 snaps and had six tackles.

Snow was part of Dantonio’s final recruiting class in 2020. He spent the early part of his career at Michigan State as a defensive back before switching to linebacker prior to the start of the 2022 season.
