Dolphins hire GM Dennis Hickey: F Grade
Dennis Hickey was with the Buccaneers beforehand, so I'll let Charlie Campbell handle the write-up for this grade:
Sources with the Buccaneers told WalterFootball.com that internally, many staff members expected director of player personnel Dennis Hickey to be let go after the draft. Many around the league and with the Buccaneers were surprised that Hickey wasn't fired with former general manager Mark Dominik and head coach Greg Schiano. Hickey took over running the Bucs drafts in 2006, and their poor performance in the drafts played a huge role in the Bucs' 28-52 record over the past five seasons. Sources with the Buccaneers said that Hickey's future would be up to the new general manager to decide, but many staffers didn't believe he'd survive the post-draft turnover in scouting departments.
Some sources found it laughable that Hickey was interviewed for the Dolphins general manager position and believe that was further proof that Miami owner Stephen Ross doesn't know what he's doing. Some in the league view Hickey as a coach and general-manager killer. In the scouting community, Hickey has the reputation of making a lot of poor evaluations that have led to a plethora of busted picks for Tampa Bay. Making matters worse, Hickey has terrible people skills; some of the Buccaneers' top scouts left the team because they didn't like working with him. The Patriots, Jets and Bills just got a gift.
