Continuing a position-by-position look at the Buffalo Bills' roster, with an eye toward free agency and the draft:
Corey Graham: 89.9 percent
Bacarri Rambo: 62.9 percent
Duke Williams: 26.0 percent
Aaron Williams: 17.7 percent
Jonathan Meeks: 1.5 percent
Josh Bush: 0.0 percent
Stat of note: The Bills allowed six touchdowns on passes that traveled at least 25 yards, which was tied with three other teams for fifth-most in the NFL.
Pending free agents: Rambo (restricted)
2016 cap hits (position rank):
Aaron Williams: $6.1 million (14th among safeties)
Graham: $4.675 million (21st among NFL safeties)
Duke Williams: $792,563
Phillip Thomas: $525,000
Jonathan Dowling: $525,000
Money line: With the Bills' tight salary-cap situation this offseason, there was speculation that Graham could be a possible cut, but general manager Doug Whaley spoke about Graham in a radio appearance last week as if he will be on the team next season. Even though Graham was graded 48th among NFL safeties this season by Pro Football Focus, he adds value as a versatile, four-down player who plays on special teams and brings a veteran presence in the locker room. Meanwhile, Aaron Williams' situation still bears watching. He has stated that he won't know for sure until training camp if he can resume playing following a neck injury last September. If Williams can't resume his career, his contract naturally becomes troublesome for the Bills.
Market watch: Pending free agents include Eric Berry, Reggie Nelson, Eric Weddle, Rodney McLeod, George Iloka, Husain Abdullah, Isa Abdul-Quddus, Rashad Johnson, Roman Harper, Walter Thurmond, Tashaun Gipson, Chris Conte, Charles Godfrey, Antonio Allen, Jaiquawn Jarrett, Ryan Mundy, Tyvon Branch, Rafael Bush, Andrew Sendejo, Sean Richardson, Larry Asante, Dwight Lowery, Rambo (restricted), David Bruton, Robert Blanton, James Ihedigbo, Robert Golden, Quintin Demps, Tavon Wilson, Nate Ebner and Craig Dahl.
Draft need: Medium -- As long as Aaron Williams is healthy enough to play and Rambo is re-signed, the Bills can get by in 2016 without adding another young player here. However, the long-term outlook is much less certain, especially if Aaron Williams can't play. Neither Duke Williams nor Jonathan Meeks has shown in three NFL seasons that they are more than role players on defense, while Graham will turn 31 this summer and is closer to the end of his career than the beginning. There's no pressing need for the Bills to grab a safety in the first round, but a mid-round addition would help at this spot.
Crystal ball: It's impossible for Aaron Williams, the team or any reporter to know what will happen when he begins full-contact practices again this summer. Because of that, the Bills would be smart to plan as if they won't have Williams available. That might mean making Rambo a priority among their seven restricted free agents, or it could mean adding another free agent to bolster the depth at the spot. The wise play would be to stack an extra layer of depth at this position and hope that the health of the group holds up better this fall.
Quote of note: "The confidence has always been there. But it's all about that first hit. When that first hit gets done, that's when I'll know if I should continue playing this game or it's time to move on to a new chapter." -- Aaron Williams on his neck injury, Dec. 10.
