I'm not optimistic. At the end of the day it is almost always about money and the Broncos have much more to spend. Agents get a percentage of the contract so Condon will 'advise' Manning to take the offer that ensures Condon the most money, although he won't frame the decision that way.
Ross and Ireland have only limited role in this.
I recall when Reggie White became a FA (in the early days of free agency). As an ordained minister he kept stating publicly that he wanted to choose a city/community where he could continue his ministry in an inner city.
At the end of the day he chose Green Bay, WI. Not exactly known for their large inner city population. What Green Bay did offer (coincidentally) was the most money.
So call me jaded, but I would be shocked if Manning chooses the Phins.
