FLOWERY BRANCH, Ga. -- Atlanta Falcons coach Dan Quinn singled out several pass-rushers while reflecting on Day 1 of organized team activities (OTAs) Tuesday.

Quinn mentioned Adrian Clayborn, Kroy Biermann and rookie Vic Beasley as players who caught his eye in third-down situations.

"The big thing that we're going to preach is trying to move the quarterback off the spot; how many times can we get that quarterback to move," Quinn said. "So the speed and the effort and the way that we come off the ball, that's some of the things that you try and implement on third down. Some of it was pressure, some of it was rush so for the first day, I have to take a look back at the film.

"I thought inside, Clayborn was one that jumped out. I saw Beasley jumped out for one. Biermann, I thought, had a good one. Those three jumped out in that period (where) we had about eight plays of third down competition at the end where you win it or lose it based on that down and distance.''

There was a couple times throughout the day when Beasley dominated left tackle Lamar Holmes, including on a bull rush. Beasley also showed off his spin move and got grabbed around the neck by undrafted rookie offensive tackle Matt Huffer.

So what does Quinn think of the spin moves?

"I think it depends on the player," Quinn said. "If a guy who has really good sudden [movement] and can spin, then it's something that we'd utilize. And if it's a bigger guy who uses more power, well, we kind of avoid it. So it's really like as a player, knowing who you are. If it's something that a guy who's got great quickness can use, we'll use it. And if it's a guy who doesn't have that kind of quickness, then we tend to stay away from it.

"If you can't shoot from the top of the key, we're not going to put you out there."

The Falcons sorely need to upgrade their pass rush. Their 83 sacks over the last three seasons are the fewest in the NFL over that span.

Here are some other observations from the first day of OTAs:
