It’s starting to look as if the NFL lockout will affect training camps this summer, but that hasn’t stopped speculation about which team will be the focus of HBO’s popular documentary series, “Hard Knocks.”
So far, teams such as the Buccaneers, Lions and Vikings have reportedly turned down the network’s advances.
The Ravens, months removed from their win in Super Bowl XXXV, were the team under the microscope during the inaugural season of “Hard Knocks” a decade ago. Only the Cowboys have been on the show twice, but if everyone keeps saying “no” to HBO, the network might have to bring back another team they covered in the past.
