I've been assuming that we'll have to end up giving one of them 3.5--4 million for a year, unless somehow it could be more incentive laden which I have my doubts on. Maybe even a 2/6 deal with some incentives would be enough, depending on the specifics.
My personal cost prediction may be off of course, and I obviously hope that it'd be something closer to 3 million, but I've been leery about some of the figures of 2 million--2.5 million etc that posters have been throwing around. I don't think it could possibly be that low, despite the market this year.
I have the feeling that the Pats have about a 3 million dollar max window they are willing to offer though, with some of that being incentivized for health and production.
Of course that was one of the reasons why I figured a 99% chance that Dumervil wasn't even being considered in the 'real' world outside of patsfans, due to the cost involved and the overall snaps and participation/fit etc.
