TAMPA — How many defensive backs do the Tampa Bay Buccaneers need?The answer: As many as it takes.With the selection of Central Michigan cornerback Sean Bunting, Auburn cornerback Jamel Dean and Kentucky safety Mike Edwards on Friday, Tampa Bay has picked a league-high nine defensive backs in the first four rounds of the NFL draft since 2016. It has picked six in the past two drafts.Despite their investments in their secondary, the Bucs allowed opponents to complete 72.5 percent of their passes last season, the second-highest percentage of all time. They also allowed a 110.9 passer rating, the second-highest rating of all time.Perhaps their new trio of defensive backs is the cure. When targeting Bunting’s coverage last season, quarterbacks completed 46 percent of their passes and posted a 41.5 rating. When targeting Dean’s coverage, they completed 42 percent of their passes and posted a 60.0 rating. Edwards is the most versatile of the bunch; he can cover slot receivers, blitz and defend the run. Each player intercepted two passes last season.After defensive backs tumbled down draft boards Thursday, teams snapped them up Friday. Bunting was one of 11 taken in the second round, the most since 2017. Tampa Bay, of course, made one of those picks: safety Justin Evans.Bucs coach Bruce Arians saw the run coming.“It’s going to be an intriguing day because there was no run on corners yesterday,” he said before the draft restarted. “Boy, there’s some first-round corners. People in the first 10 picks (Friday) are going to get really quality, maybe first-round players.”General manager Jason Licht made a trade on Day 2 of the draft for the fifth straight year, sending the Bucs’ No. 70 pick to the Rams for picks No. 94 and 99. He used the No. 94 pick to take Dean and the No. 99 pick to take Edwards.Did Tampa Bay win the deal? It depends which calculator you use. If you go by the draft pick value chart devised by former Cowboys coach Jimmy Johnson , it’s a nearly even deal. If you go by Football Perspective’s chart , which more accurately reflects the value of picks, the Bucs come out ahead. Basically, they received $1.46 in return for their dollar.In 2015, Licht traded picks to acquire offensive guard Ali Marpet and later linebacker Kwon Alexander. In 2016, he traded picks to acquire kicker Roberto Aguayo. In 2017, he traded picks to acquire linebacker Kendell Beckwith. Last year, he traded picks to acquire offensive guard Alex Cappa.The Panthers have checked off their top two needs. After selecting Florida State edge rusher Brian Burns with the No. 16 pick Thursday, Carolina traded up to No. 37 to take Ole Miss offensive tackle Greg Little on Friday. Little allowed 26 pressures over the past two seasons. With the 100th pick, Carolina took West Virginia quarterback Will Grier. The Panthers hadn’t drafted a passer since 2011, when they took Cam Newton at No. 1.The Saints, because of last year’s trade up for defensive end Marcus Davenport, didn’t make a selection until halfway through the second round. At No. 48, New Orleans selected center/guard Erik McCoy, who surrendered only one sack in 1,500 pass blocking snaps in his three seasons at Texas A&M. He was their one and only Day 2 pick.The Falcons didn’t have a Day 2 pick. They packaged their second and third-round choices Thursday to move back into the first round for Washington offensive tackle Kaleb McGary. They drafted Boston College offensive guard Chris Lindstrom with their original first-round pick.San Francisco paid tribute to scout Reggie Cobb by bringing Cobb’s son, DeMarcus, to Nashville to announce the team’s second-round pick, which was South Carolina receiver Deebo Samuel. Cobb, who was selected in the second round of the 1990 draft by the Bucs, passed away April 20. He was 50 years old. He was a running back in Tampa Bay for four seasons. In 1992, his best season, he rushed for 1,171 yards and scored nine touchdowns. Contact Thomas Bassinger at firstname.lastname@example.org . Follow @tometrics.
