This one is a tough one though.
Jimmy Smith is one of the Ravens better players on defense. Not saying Gilmore is not for the Bills, but he's had his bumps in the road.
Gilmore did have an average start to 2014, but rebounded.
In 2016 the cap space will be tighter. Gilmore's option is picked up if I recall, locking him into the 2016 cap. It will be interesting to see his price.
