First, however, the rookie will have to get past being star-struck by his teammate.
"He introduced himself to me. When I went up and met him, it was like, 'Holy cow, that's Drew Brees,'" Grayson said after rookie minicamp on Saturday, per The Times-Picayune. "It's still kind of like the deer in the headlights. It's a dream come true for me to be able to have this opportunity to learn from one of the best quarterbacks of all time."
Grayson admitted he has a lot to learn and planned to tweak his mechanics.
"As a competitor, I always say I want to play right away," Grayson said. "But that's something I said through the process. I told all the teams I met with, I have no problem sitting and learning from a guy like Drew Brees."
Coach Sean Payton praised Grayson's decision making, arm strength, intelligence and "very accurate" passing during the team's rookie minicamp this weekend.
