Outside of individual workouts, 2012 NFL Draft hopefuls have just one way to impress potential NFL teams and scouts following the scouting combine: pro days. Scouts will pack their bags, hit the road and try and find something in each player they can possibly evaluate that they've missed through the hours of tape they've certainly seen up until that point.

A solid pro day can make a player's draft stock, and solidify him in a specific round or spot in a round. They're better for some positions, and not so great for others. For instance, some don't like quarterback pro days since it's such a controlled throwing environment, while other positions can benefit just from seeing what kind of shape they're in with time off.

The NFL released official pro day schedules, and for the Detroit area, mid-March is where it's at. Michigan State will have their pro day on March 14, along with teams like Oklahoma, Florida State and more. Michigan will be March 15, sharing the day with Virginia Tech, among others. Prior to both of those will be Western Michigan on March 13 and Central Michigan on March 12. For a full list of schedules, go here.
