First and foremost, Miami must win out.
W need 3 of 4 teams to vave 3 ACC losses or hold the tie breaker against them. The only team Miami would hold a favorable tie break is GT, if GT loses another gsme. They play Pitt in 2 weeks.
If GT wins their last 2 ACC games, we would need Louisville, Virginia, and SMU to have 3 conference losses for Miami to get the ACC title game. It'sunlikely SMU loses 2 more ACC games. It's possible Miami could hold a tiebreaker with UVA if UVA loses to VT. Miami would have beaten VT, but UVA beat Louisville wirh Miami losing to Louisville. In this scenario Miami would the tiebreaker with UVA due to better conference wins.
Miami's best possible changce is for Pitt to beat GT, Clemson beats Louisville, and VT beats UVA in their final game of the season. Miami would face SMU in a rematch game in the ACC title game.
There is a path to Charlotte.
