Yes, Wilfork accepted being paid the average of the top 5 NT's like a man. If Mankins is offered the average of the top 5 guards to sign a one year contract for 2010, I'm sure he will take it like a man also. This is a Samuel situation, not a Wilfork one.
And just BTW, the team decided that Wilfork is a key element to the defense, and one of the highest 2010 priorities for the team. I don't think that team the considers Mankins in the same situation. I certainly don't. I want us to sign Mankins, but personally I think that it was more important to sign Wilfork and Bodden (and extend Brady).
In the end, I don't think that this situation should be a surprise.
