The 2016 NFL Combine is officially underway, with the first prospects arriving on Tuesday. Things kick into high gear on Wednesday for this first group, but Tuesday evening brings a critical part of the process. Tuesday is the first day teams are allowed to schedule interviews with players. They can interview players in each group over three days, but there are limitations. I don't remember the exact number, but I think it is 30 or 50 interviews over the course of the week.
Former NFL defensive end Austen Lane went through the Combine process back in 2010 when he was a fifth round pick of the Jacksonville Jaguars.
