The Tampa Bay Buccaneers are after defensive Ron Parker, according to Rand Getlin. They'll have to beat a number of teams to get him, as Getlin also mentions the Atlanta Falcons, the New York Jets, the New York Giants and his old team, the Kansas City Chiefs.
Parker was an unknown who'd spent time with four different teams since entering the league in 2011, but he earned a starting job as a strong safety and cornerback, playing a whopping 1,037 snaps over the season. His versatility is what makes him valuable, and I'd expect the Bucs to primarily see him as a slot cornerback/strong safety hybrid, as they already have Bradley McDougald at strong safety.
Parker is likely to cost a pretty penny though, given his interest on the market, and his price could be as high as $6 million per year. At that cost he's going to have to be a major part of the team's defense to be worth it. It'll be interesting to see how the Bucs plan to use him, if they get him to sign a contract in Tampa.
