Is that a worst coach or worst announcer card?
Kliff Kingsbury had Patrick Mahomes as the starting QB at Texas Tech for 2+years and had a losing record with him. As a reward for that epic accomplishment he got the head coaching job with the Arizona Cardinals. He immediately jettisons the previous year's first round draft pick, Josh Rosen, to Miami (good move) and then turns around and drafts Kyler Murray with the first pick in the draft (horrible move). Needless to say things did not work out for all involved.
As far as the worst announcer in pro football I shall not say anything or I will be accused of being Romophobic ............which indeed I am.
