First, let me say that I'm just speculating on all this. However, if other NFL teams are a guide (and I think they are), I think you will have the same timeframe for putting in for seats as everyone else. It just depends on where you are in the queue.
For the Baltimore Ravens, for example, (my dad has season tix), they mailed a form to fill out with your top 3 choices. They broke the stadium up into tiers based on PSL and season ticket cost. You ranked your choices, 1,2,3. You had to have the form in by a certain date. The Ravens then went through the list of requests and assigned seats. Everyone was given a place in the "line". Season ticket holders were given their place based on where their seats were in Memorial Stadium. Non season ticket holders were given a place based on when they turned in their form. When your name came up on the list, they would look at your choices. If no "choice 1" seats were available, they'd drop to choice 2, etc.
Again, all my speculation and I'm only posting this because it's fun to speculate, even though we'll know for sure within a week. Good luck.
