Free-Agent Setup: Bucs focus on defensive line

The Tampa Bay Buccaneers already decided to part with running back Doug Martin and defensive tackle Chris Baker, who were released Feb. 20. The team is undecided about the future of defensive ends Robert Ayers and William Gholston, who could become free agents. The biggest area of need is on the defensive line. To that end, they will consider bringing back free-agent defensive tackle Clinton McDonald, who had five sacks with a late-season surge. Also, defensive end Will Clarke, who joined the team during the season, had 2.5 sacks. Two players the Bucs will be focused on are contemplating retirement: cornerback Brent Grimes, who tied for the team lead with three interceptions and quarterback Ryan Fitzpatrick. Grimes will be 35, but his play belies his age. His 20 interceptions ties Richard Sherman for the most in the past five years. Fitzpatrick went 2-1 as a starter last season. The Bucs are uncertain about the outcome of the NFL investigation into Jameis Winston and a complaint that he groped a female Uber diver in 2016. So, it's imperative the Bucs secure a No. 2 quarterback who could win immediately. Unit-by-unit depth chart as of Super Bowl LII.
