If we are just going to dream let's beat Alabama & Clemson & Ohio State & Oklahoma & LSU & thump 7 PAC 12 teams but that doesn't seem very realistic.
The current status quo of 7-6 seasons hoping for a crappy bowl game sucks and I don't see that changing any time soon if BYU stays independent.
I do think BYU could rebuild to compete for AAC championships and possible playoff berths which seems absolutely amazing at this point.
