Groves, 31, offers some positional versatility to the Bills along their banged-up defensive front seven. At 6-foot-3 and 265 pounds, he has experience playing as a defensive end in a 4-3 scheme and as an outside linebacker and inside linebacker in a 3-4 scheme.
Groves is joining his seventh NFL team after previous stints with the Jacksonville Jaguars, Oakland Raiders, Arizona Cardinals, Cleveland Browns, Houston Texans and Tennessee Titans. A second-round pick by Jacksonville in 2008, he has generally been a disappointment as a pass rusher, posting 9.5 sacks in 100 career games (32 starts).
One NFL GM recently told Caplan that he saw Bryant, who turned 31 in April, as a part-time player and would only use him on 20-25 plays per game.
