"No one really knows whether Brett Favre will retire this time around. Favre apparently doesn't know either, with reports saying he's texting teammates he's done one day, then saying he will play if he's healthy the next day.
So this little saga might play out for days or weeks before the uncertainty is resolved. But this much, at least, is certain:
If Favre decides not to play, the Dolphins would be wise to involve themselves in the drama.
If Favre leaves the Vikings now, after the team bet everything on his return by not drafting a quarterback or trading for Donovan McNabb, the Dolphins should try to take advantage of the situation and offer to bail out the Vikings.
Jeff Ireland should call Rick Spielman and offer quarterback Chad Pennington."
