The 6-foot-2 Grayson started the past two seasons at Colorado State. During his senior season, the quarterback compiled 4,006 yards on 64.3 percent passing with 32 touchdowns to just seven interceptions.
The 23-year-old played in a system in college that relied heavily on his ability to read, adjust to coverages and make checks, an asset scouts valued when assessing Grayson's ability to comprehend and adjust to a pro playbook.
Grayson displayed good touch on his deep ball in 2014, something coach Sean Payton clearly values in his passers. He also deploys a deft ability to get the ball out under duress.
Brees isn't finished yet, but the Saints needed an eventual contingency plan and targeted a quarterback this season. Now Payton has a few years to build Grayson into the type of quarterback that will make it an easy transition when Brees decides to hand off the torch.
