Total speculation on my part, but this is how I'd expect it to play out and similar ot the numbers I used a few months ago. They'd be a little higher now post Super Bowl.
-Brown seeking $10M range
-Bucs offering $5-7M...or maybe more, but incentive-based
-Maybe there's a team willing to offer more guaranteed or somewhere in the $8M range
-Bucs will have a decision to make on whether or not to come up
-Brown will have a decision to make on whether or not to play for less
That's just based on my understanding of the market, what I'd be looking for if I'm Brown, and what I'd be willing to do if I'm the Bucs.
