General Manager Thomas Dimitroff said the team did plenty of research on Moore, who had a private workout with the team.
Dimitroff said Moore will play strong safety for the Falcons, but his speed (he ran the 40-yard dash in 4.51 seconds at the Combine) provides some flexibility.
He returned four of his 11 career interceptions for touchdowns and leaves Missouri with 284 tackles.
“He’s going to add speed and urgency: Everything we’ve talked about with our defense,” the general manager said. “We’re fortunate he dropped to 55.”
Moore said he immediately connected with Dimitroff and Head Coach Mike Smith and hoped he ended up in Atlanta on draft day.
May experts had him as a top-10 or 15 pick after his junior season but injuries limited his time as a senior. The resulting slide was troublesome, but expected.
“It was very tough, especially since I know what I can do and I know what type of player I am,” he said. “When I slipped, I just thought about what my mom said. Everything happens for a reason and this has to be the reason.”
Moore’s known for a devotion to the game and his teammates. He wears No. 25 in honor of friend and former Missouri linebacker Aaron O’Neil, who died during summer drills in 2005.
Even though injuries have kept him out of games, he has a record of playing through pain.
“That’s just the kind of person I am,” he said. “I’ve been playing rough ball my whole life. A tweak here or there is part of the game. If you don’t have those you’re not playing hard enough.”
