We don’t yet know who will appear on HBO’s “Hard Knocks” during NFL training camp. But according to a report, the Cleveland Browns will not be featured. “The Browns were one of eight NFL teams that do not meet any of the three exemptions for opting out, if drafted,” ESPN’s Tony Grossi reported. “But the league and producers of the popular reality series have multiple teams interested, per the source, and the Browns will get their wish again to avoid the scrutiny of HBO’s cameras.” Both head coach Hue Jackson and defensive coordinator Gregg Williams have been on “Hard Knocks” in the past. Grossi added that “the overwhelming sentiment with the Browns was they don’t want the distractions inherent in the series while they attempt to dig out from the rubble of last year’s 1-15 season.”
