Combine about more than workouts

We're not expecting to see much of Stanford QB Andrew Luck and Baylor QB Robert Griffin III at the NFL combine, and other big names such as RB Trent Richardson (Alabama), S Mark Barron (Alabama) and WR Ryan Broyles (Oklahoma) won't work out for medical reasons.

Still, approximately 300 players will take the field for workouts. And, most importantly, 328 invitees will be in attendance to interview with teams, take psychological tests and undergo medical examinations.

Here are some of the prospects to keep a close eye on as the combine progresses.
