The Buffalo Bills haven't been big spenders in free agency. They've signed just one player - linebacker Manny Lawson - and dropped quarterback Ryan Fitzpatrick since the league year opened. They also allowed big-money free agent Andy Levitre to depart to Tennessee.
Lawson's 2013 cap hit is a relatively low $2.4 million. According to NFL.com, that leaves the Bills with $16,851,532 in cap space. That's a pretty specific number, and it stands as the seventh-highest amount of room in the league. Just as in previous years, any money the team doesn't spend can be rolled over into the 2014 season next spring; keep in mind that part of that will be allocated to this year's class of rookies, as well.
Buffalo still has several spots available in the starting lineup - potentially including roles at left guard, linebacker and strong safety - they could conceivably fill via free agency. That's not to mention that pesky quarterback situation and depth across the offensive line, linebacker corps and secondary. For now, however, the Bills appear content to play the field cautiously.
