The Raiders’ Signals
The Raiders have made some horrible coaching decisions over the past couple of decades. Jon Gruden did a decent job during his first spell with the franchise. This attracted the attention of the Buccaneers and they lured him to Florida. Al Davis didn’t fight him and held out for several high draft picks (via NFL.com).

Naturally, the two teams met in the Super Bowl but the Raiders handed the initiative to Tampa. Nobody knows why Oakland’s new coach, Bill Callahan, didn’t change all of their signals. This meant that Gruden knew what was happening and the Bucs destroyed Rich Gannon. The usually-reliable Gannon threw a ridiculous five interceptions.
