I would agree (here) as well, Greg.
We've hashed this so much, it's just plain redundant.
Favre has probably been looking at the caliber of protection he'd see once the Game starts. Left Guard, and Center are top priority, for just about "any" Quarterback. TT has made sure to stock the larder with some better (and taller) Wideouts, making the Packers resemble the Lions when they had Herman Moore, ...almost.
If McCarthy and Thompson can sufficiently answer hard questions on those two positions, in a solid fashion, then I would think the next day, Brett would be on the four-letter network announcing his decision to return.
Truthfully, it's mute point - he doesn't have to say anything; and MM doesn't have to give him a free pass on the mini-camps, either - like Sherman would always do. I've always felt Favre should have more of a Majik Man attitude for the off-season than he has.... his INT stats demand he should be out there on the field watching his fundamentals and his decision skills constantly, which sagged under Sherman, year after year. of late....
Spending time, in the offseason with the rest of the Team wouldn't hurt him at all - and the Team wouldn't be so off-key, either...
I'd say that this year, if he does come back - then TT & MM (both) should demand his FULL participation throughout the whole offseason - no question about it.
