Bears chairman George McCaskey hand-delivered injured tight end Zach Miller his “touchdown” ball in the hospital Tuesday. And it was a touchdown — regardless of what Alberto Riveron, the NFL’s senior vice president of officiating, maintained in his weekly video Wednesday. His explanation made his decision to reverse Miller’s 25-yard touchdown more egregious. It was a ludicrous justification. Dean Blandino and Mike Pereira — the officiating bosses who preceded Riveron — were right to strongly criticize Riveron’s call on various outlets. “I’m tired of having to come on this show and say, ‘Why are plays being reversed when we can’t find anything?’ ” Pereira said on his online show, “Last Call,” with Blandino.
