MAIMI GARDENS — The Miami Dolphins’ worst fear, the nightmare scenario they never wanted to admit to or confront, became harsh reality in Sunday’s 28-27 loss to the Arizona Cardinals — their problems go beyond quarterback Tua Tagovailoa’s absence. The Dolphins are now 9-8 in Tua’s past 17 starts. Tua has 24 touchdowns and 15 interceptions in that span. This team needs more than Tua to win games. Realists always knew this was the case.
