Hi there!
Your GPA is okay, it could be a litter better. It wouldn’t hurt to raise it a bit 
Since you state, you played multiple sports, I think you’re going to go into MSU doing sports as well. There’s a lot to qualify for sports, especially trying out for the actual sport itself.
What about the SAT test scores? Those are valuable for every college entry.
Also it is dependent on how consistent your grades are on your transcript. This applies to not only MSU, but many colleges. You have done a lot of extracurricular activities, I would consider picking a major that you want to go into any college with, even if it undecided. If you like a well rounded school with both Science and Arts, MSU is for you!
Good luck! ;
