I know I'm in the minority on this and I know many posters on here believe that VATech and Miami are where we want to be, but I believe we are better off with Clemson and FSU.
1) VATech is, and has been, essentially a paper tiger. Beamer used weak scheduling to build his record. His greatest years are when the league big boys were own. I'm not convinced that VATech will be back to the top of the ACC on a long term basis. Rutgers merely copied his formula. I'm not sure Beamer will be around much longer, either.
2) Miami is Miami. Can they win without cheating? This remains to be seen. Lately, they can't win with cheating (I think they were copying UNC).
3) Clemson is the historic big dog in the ACC. This is pre-FSU, but they ruled the roost, for the most part.
4) Since joining the ACC, FSU has been the biggest of the big dogs.
5) VATech does not consider us their rival, though we have had many good games, they hate UVA, WVU and Miami, two which they still play.
6) Miami never saw us as a rival.
7) Clemson and FSU are a clean slate, no significant history there.
8) Clemson and FSU are built to dominate for a long time.
9) We have been rebuilding a tough program. HCDM did very well to put us on solid footing.
10) HCSS will continue our return to ranked footfall (not there yet, but the CFB world is watching).
11) We are the only team that will be tough enough to put a hurt on Clemson or FSU. We may not win, but they will remember us. When SU and PSU renewed the old rivalry, Paterno commented on how hard Syracuse was hitting. We've only improved, offensively and defensively.
Anyway, I think in the long run, we will benefit more by not being "old Big East" and playing more against the historical powers. Just my take.
