Atlanta has talent on offense. They are not rebuilding the entire team, not with Ryan and AJ, so they need to get personnel that understand the Quinn D, and now. The South is an easy pickings division right now, he isn't competing with a great division. I won't be surprised to see a few Ex Seattle players on that squad by season's beginning, like with Jax. The owner was adamant when he fired the old coach that this was a win now move. Quinn's feet aren't to a fire, but results are expected to be quick.
Add to that that the Seattle D model is the NFL darling right now, can you believe what Philly paid to get one of the corners and what the Raiders paid for a backup linebacker, and a 2nd for Irvin becomes a correct price because competition for services next year. I don't for one second thing the Falcons have not reached out to Irvin's agent, if this thing goes down there will be a contract understanding in place. Tampering schmampering, that is what happens in the NFL. I am pretty sure when Boldin went to SF there were assurances in place, and that was for a 6th.
