I suspect a lot closer than many think (especially those that still consider him untouchable).
NOT after this season, obviously--the winning record AND the preceding several seasons give him a "do-over" if he wants one, which he apparently does.
It isn't so much the record that was/is/will be the issue, but Meyers own approach and demeanor; against the background of last year's self-induced "drama" and this year's strange "disconnect", a dig-in-his-heels refusal to remove Addazio at OC could create the conditions that force Foley to make a change at the top after 2011--especially if it doesn't work, and our team's play does not improve. We've talked about all the reasons, pressures and forces-at-work-behind-the-scenes.
Mind you, even then I would anticipate a seemingly "amicable parting of the ways", perhaps even one of those "retiring to spend more time with my family"-scenarios. Hell, that one's already warmed up and sitting out there, ready to go.
