After Los Angeles, Miami is hands down the worst sports city in America- bar none. If the NFL still had the blackout rule Dolphins fans would have never seen a home game on TV the past decade.
I used to scout Hurricane games live in the final years of the Orange Bowl when they had a decent team- the upper deck was always near completely empty. One game (WVU) i went up there- bird sh!t on all the bleachers- utter adnomination.
Even when the Miami Hurricanes were winning Natties, their attendance was horrendous. They would only sell out if UF and FSU or big names like Notre Dame or Oklahoma came.
