Gibson, 3 years younger than Price, received a 3 year deal $30 mill offer for a $10mill AAV.
Godley, 5 years younger than Price, received a minor league contract.
Price was the oldest and least durable of these pitchers. He has a big name, and an excellent resume. But to think he would get the same AAV as the other big name in Bumgarner is probably a bit of a pipe dream, especialyl given the differences in age and IP. It's hard to say exactly where the market would have placed him, but a 3 year $16-17mill AAV is absolutely best case scenario if it was possible at all.
The only reason to pay that much for Price is if a GM thinks his name still carries significant PR weight so as to bolster ticket sales...
