Looks like there is a new GM philosophy out there called "cash to the cap." It's where teams will no longer amortize the signing bonus in their budgets. The league will still consider the signing bonuses amortized for cap purposes, but these teams will not spend over the cap in real dollars.
In other words, if they sign a guy to a 5 year $40M contract with a $5M signing bonus and a salary of $4M the first season, they'll factor in $9M against their spending for the season. And once they reach the cap number for that season they're done. So they'll essentially be spending less money than everyone else every single season.
The estimate I read said that there are possibly around 10 teams going to that approach now. My team, the Bills, is one of them.
So even though the Bills have ~$30M under the cap, the odds are that they won't be big players in the FA market.
