Cordy seems to be happy in Buffalo, team stuck by him through his medical issues. Nothing got leaked about it until the story broke as justification for the award nomination. Best case scenario is that he feels some loyalty to the team and takes the hometown 'discount'.
Richie is a tough one because nobody else on the open market has his circumstances. He has stated that he wants to stay and, quite frankly, I think he owes Rex. Teams weren't knocking down his door trying to get him under contract. Personally, I'd offer a 3 year deal with that 3rd year as a club option to protect from falloff of production from age.
Gilmore's contract is going to hurt his doubters when they read the details. Joe Haden is the spanner in the works. $13.5m a year average and he's really not very good. Even if sense prevails on the benchmark, it's going to be 8 figures a year in some way, shape or form.
