There is no restriction on how many ACC teams get in... That's not how the selection process works at all... Wake or Syracuse getting in doesn't hurt GT any more than USC or Marquette getting in.
We are most fighting for a spot against several other teams: Vandy, Xavier, USC, Cal (who lost by 30 last night), Rhode Island, Kansas St, Georgia, Illinois, Providence, Marquette, Arkansas, and maybe even Seton Hall and Michigan.
If Syracuse beats us, they are almost definitely in unless they get smashed in their 1st ACC game. If we beat Syracuse, we are probably in, but might need 1 more win. No one that wins tomorrow is going to need 2 ACCT wins to get in.
