The next step on the road to the NFL Draft is the Scouting Combine in Indianapolis, which begins next week.
After the combine, players return to their campuses for Pro Days.
Among the advantages for quarterbacks at their Pro Days is that they get to throw to their own receivers, players they've thrown hundreds of passes to and are comfortable with. They also go through a scripted routine of throws.
The advantages for coaches, scouts and executives of Pro Days is the opportunity to see a player in his own environment and also spend more time with them. The combine allots 15 minutes for a player interview; no such limits apply to Pro Days and teams often arrange extended visits in the day before or after the workouts.
With Bills fans having their eyes on quarterbacks, here are the scheduled Pro Days for six of the top prospects:
Baker Mayfield, Oklahoma, March 14
Mason Rudolph, Oklahoma State, March 15
Josh Rosen, UCLA, March 15
Sam Darnold, USC, March 21
Lamar Jackson, Louisville, March 29
Josh Allen, Wyoming, March 23
