The 2012 NFL Combine, the biggest event of the NFL's pre-draft season, kicks off Wednesday, with kickers, punters, offensive lineman and tight ends set to arrive in Indianapolis.
To better manage the crowds, the more than 300 college stars attending this year have been divided into four groups, with the marquee skill position players like Baylor's Robert Griffin III and Kendall Wright not set to arrive until Thursday.
Each group will undergo orientation on their first day, before submitting to media interviews, official measurements and psychological testing on Day 2, interviewing with various interested NFL teams on Day 3 and finally beginning the all-important workouts like the 40-yard dash on Day 4.
The defensive backs, the position group the Dallas Cowboys have been linked the most to in the first round of mock drafts, aren't set to arrive until Saturday and won't run the 40 until Tuesday, Feb. 28.
