NFL's Ed McCaffrey Furious Over Duke Ref Blunder ... It's An Absolute Travesty

Ex-NFL great Ed McCaffrey is still LIVID that his son's Duke football squad got hosed by the officials this weekend -- telling TMZ Sports they deserve a HARSHER punishment than a 2 game suspension.

Ed's son is a WR on the team -- which makes the whole thing sting even more for Ed ... who says the blown call on the final play of the Miami vs. Duke game was, "The most egregious officiating debacle I’ve ever seen since being a part of football."

Of course, the refs missed FOUR mistakes on a wild final play, in which Miami took a series of laterals all the way to the house ... resulting in a 30-27 victory.

"The ACC did the right thing by suspending [the officiating crew] for two games," McCaffrey said ... "But if it was up to me I would’ve suspended them for the rest of the season."

"Then I’d evaluate them at the end of the season to see if they deserve to return to officiate next year."

Ed says he feels terrible for the players who are still in the hunt for an ACC Coastal title -- because "They can’t get the win back. It dropped Duke out of the Top 25 so this is really disappointing."
