SMU, Clemson and Miami all look good to go undefeated the rest of the way. We have seen Miami in a bunch of tight games to mediocre teams, but keep winning. Their schedule doesn't get much harder if at all. SMU also pulled out a ridiculous game last week, but if they hadn't gone -6 in TO's likely would not have been close. They haost one tough game and then play 3 of the lesser teams in the ACC. Clemson has a harder schedule than the other 2 but also has been beating everybody they've played by 2+ scores.
Pitt, also undefeated has to go to SMU and does play Clemson. They could figure in big time
Anyway, if all 3 go undefeated basically means you make your tiebreaker in that conference goes to the top 2 teams with the best in conference opponent win %. Currently SMU sits in at 7/14 W/L with Pitt and 3 pretty bad teams 7/10 combined the rest of the way so 14/24, Miami's opponents sit at 7/13 with 9/9 left so combined 16/22 , Clemson 7/18, but has 9/3 left so 16/21.
As it stands SMU is in the worst spot to make it to the CCG if chalk holds. That being said, Clemson has 3 tough games left, Miami doesn't have much and SMU has Saturday and should roll if they make it past Pitt. The best shot SMU has to win the ACC is to have Clemson lose one of their remaining games.
A win over the ACC champ would look great and probably bump the B12 winner up from 4 to 3, but a win over what's likely to be a #13 or 14 ranked CFP team on the road is still a really solid win that would look solid
