FLOWERY BRANCH – Falcons coach Dan Quinn promised that there would a lot of experimentation this offseason after evaluating the talent on the roster.

In some salary cap and scheme-fit moves, the Falcons parted ways with some of the key veterans from the 2012 NFC championship game team in left guard Justin Blalock, left tackle Sam Baker and wide receiver Harry Douglas.

He also moved on from running back Steven Jackson, linebacker Prince Shembo, defensive end Jonathan Massaquoi and safety Zeke Motta for various other reasons -- Old (Jackson), alleged dog killer (Shembo) and injury (Motta). Not sure why they got rid of Massaquoi, who flashed some pass-rush ability and was quickly snapped up by Tennessee.

Quinn and defensive coordinator Richard Smith played a dazzling array of combinations along the defensive front this offseason, but this nickel package that lined on June 16 stood out.

LDE – Vic Beasley

LDT – Jonathan Babineaux

RDT – Adrian Clayborn

RDE – Kroy Biermann (Malliciah Goodman was out with an injury, but has a shot to earn this spot.)

LB – O’Brien Schofield and Allen Bradford.

NB – Phillips Adams

CBs – Desmond Trufant and Robert Alford

FS – Ricardo Allen

SS – Kemal Ishmael (in William Moore’s spot).

The Falcons will play a lot of Cover-3 (sending four, dropping seven, which ends up being a 4 going, 4 across and 3 deep) and the above unit has a lot of speed to close quickly into the gaps of the zone. Click here for the basics on Cover-3.

Not sure if Quinn will be able to play as much man-to-man defense as he did in Seattle and may have to send five more often to generate a pass rush and create more one-on-one matchups.

"We play man-to-man or Cover-3, not much more than that. It's not a secret." - (Seattle Safety) Kam Chancellor, January 2013

Quinn’s biggest switch ended up being cornerback Ricardo Allen moving to free safety. He ended the offseason working with the first-team defense.

Free safety Dezmen Southward’s move to cornerback didn’t work out as well after he suffered a knee injury and had surgery.

(Here's a youtube video of Allen's ball-hawking style of play while at Purdue.)

Heading into the training camp, the offensive line is the major concern. The Falcons have remained quiet, but it makes absolutely too much sense to sign two-time Pro Bowl guard Evan Mathis.

At least a half-dozen teams are interested in Mathis, but super-agent Drew Rosenhaus wouldn't name the teams during a recent radio appearance.

"Clearly Evan is one of, if not the top overall free agent right now that would be available in the NFL."

If the Falcons don’t sign Mathis, either Chris Chester or Mike Person will end up as the starting left guard. Person, who’s has zero NFL starts, worked with the first-team the entire offseason.
