According to what's going around the Fins news wire, Manning specifically does not want to play in the NFC because he doesn't like playing his brother. He also, apparently, does not want to play any more cold weather games than he has to; which means NYJ and Seattle are out. The final piece of the puzzle is that Manning wants to get this over with ASAP and I think Ross is the only guy that will give Manning whatever he wants provided he checks out medically.
I won't argue with you on whether Philbin does or does not want him. I do agree that Seattle is still in play per what was posted above.
I see due to stadium or weather the following options for Manning:
Miami - but I think Flynn who can be had cheaper maybe long term might fit better
Arizona - would have to deal Kolb, or make this a really heavy incentive deal
San Fran - west coast, good weather
Jacksonville - no mention to this point, but they got Gabbert petty cheap, and was old regime, so they could use that as an excuse. But need WRs bad, so a Wayne deal may help seal this.
for close to winning:
San Fran
Kansas City - but outdoors and cold weather team.....
Seattle - young defense is getting better, and they have rb set up. Need OL help and Wr help
I don't know if there is a mortal lock here. I think Miami is a target due to Qb desperation, and solid showing last year. Just not sure of the fit. Nor would I agree that Indy runs a WC offense.
