Alex Loehlein is an 8-year-old boy suffering from Duchenne Muscular Dystrophy. The Minnesota Vikings invited Loehlein to watch one of their practices not too long ago, and Loehlein thought it was only right that he pen coach Mike Zimmer a thank you note.

Grandpa Loehlein is right, Coach Zimmer. After losing your prize running back and starting the season 2-5, things can only be going up from here.
