Sorry, but my take is a little different (or foggy) on the ol' Orange Bowl. Now granted, I lived in Key West during the 70s and early 80s and while the games may have sold out by kickoff, they didn't within 72 hours of kickoff which they had to in order to be televised. We got Dolphins road games each week and never got home games. We had a lot of Undersea World of Jacques Cousteau from what I remember, stuff like that as filler until the 4pm game. Dolphins at home on the Monday Nighter? Get ready for Serpico starring Al Pacino at 9pm. Yeah....a lot of that going on. After a while, WPLG the ABC affiliate started buying up the last 500-1,000 tickets just to get the damn thing on the air that night. Howard Cosell announces John Lennon's death at the Orange Bowl on Monday Night Football in 1980? You might have heard about it live then but we sure didn't. We had a movie going on. Probably caught it on Good Morning America at 7am the next day.
Oh, and UM football? Please! It takes an unbeaten Miami team vs Florida, Florida State or Notre Dame to get a full crowd there otherwise, it's sparse. OB was always that way for them too.
