It's already a 100% certainty that Harbaugh is done in San Fran after this season. It's public knowledge.
I'm sure Kap would come to Buffalo for the right money. After taking a closer look at the 2015 possibilities in FA or trade, then looking at the 2016 QB free agents, I'm now pulling for the Bills to make a bold move and offer someone a huge contract in 2016 to try to steal them from their team. The following players are free agents in 2016:
Eli Manning, Big Ben, Phillip Rivers, Sam Bradford, Ryan Tannehill, Andrew Luck, Drew Brees, Russell Wilson, and Nick Foles
I wouldn't mind the Bills offering something huge like $25 million a year to steal Rivers, Luck, Roethlesberger or Drew Brees. As unlikely as you may think it would be for any of those guys to jump ship to the Bills, money talks. It would make them the highest paid QB in the league. Chargers want to match that offer to keep Rivers? Then the Bills should offer him $27 million a year. No I'm not kidding. Whatever it takes. Rivers and Brees would be the most likely to take the bait. Luck and Ben would be a huge longshot.
For the other QBs available in 2016, all the Bills would have to do is be willing to pay more than the teams trying to resign their QBs. You'd have to think out of 8 teams there has to be at least ONE that won't be willing to vastly overpay to resign their QB. It's the type of bold and unconventional move the Bills need to do to become a playoff team imo. They've had stud players at every other position at one time or another over the past 15 years and none of them got us to the playoffs. It's time to blow some serious cash on getting a QB, even if that means letting other good players walk to make cap room.
