We never have blowout revenge wins.
This struck my curiousity so I decided to list 'blowout' wins against ACC opponents.
Criteria: Doesn't matter if opponent was actually in the conference at the time of the win --I list two games against each school --a recent win where I picked 16 for the minimum margin of victory and the most lopsided win ever against the given opponent. Miami and VT will only have one game listed because the most recent victory is also the most lopsided all time victory.
BC ............'97 42-14 ..... '72 42-10
Clemson .....'89 30-14 ..... '44 51-0
Duke ........ '06 49-21 ..... '66 48-7
FSU ......... '75 30-0 ....... '55 34-0
Maryland ... '99 49-31 ..... '93 38-0
Miami ....... '64 20-0
UNC ......... '03 41-24 ..... '85 31-0
NCSt ........ '99 48-21 ..... '18 128-0
UVA ......... '06 24-7 ....... '00 35-0
VT ........... '06 38-27
WF .......... '03 24-7 ....... '20 44-0
Most wins against with 16+ margin:
Clemson 20 (many back in the days when the game was held in Atlanta every year)
Duke 19
WF 15
Of the 13 wins against Maryland 7 (from '90 - '99) have been by 17+ points.
