Fair enough on a well-run JB zone. But I think you're being a bit overly simplistic looking at just Duke, UNC, and UVA. What makes the ACC different from the most other leagues is that about 12 different teams can beat any other team on any given night. If you go on the road against Clemson, Miami, GT, Wake, BC, or ND without at least your B+ game, you're probably going to lose.
Syracuse has been in the ACC for 5 years now. Y'all have finished with fewer than 8 conference losses once, and even then the Orange still dropped 4 games (including BC and GT). So to someone who's been watching 25 years of ACC ball, I'd say expecting anything better than 14-4 is out of whack and even 13-5 is on the high end of the "realistic" spectrum.
Looks like Cuse gets a H&H with Duke, Clemson, BC, and Pitt this year. 2 losses from those 8 seem like an absolute best case scenario. Then it's road only matchups with UNC, VT, ND, NCSU, and Wake. Again, 2 losses out of those 5 feels like the best case scenario. So you'd have to run the table in the home only matchups (UVA, FSU, Louisville, Miami, GT) to get 14-4, just in the BEST case scenario.
I'll go with 12-6 for my way-too-early Cuse projection.
