NU from VT would seem to be a lateral move, if anything.
VT has advantages when it comes to recruiting. NU has an edge in that it plays in a far less competitive division in its conference. The floor overall would seem to be higher in the BIG, but the ceiling seems to be higher in the ACC.
I'm not sure how much history and tradition factor into the attractiveness of a job. When it inflates fan expectations to an unreasonable level, as is apparent here at times (no, I'm not saying right now, eight games into the season is one of those times), it would seem to be a detriment. In any case, NU would have the edge, but VT is no slouch when it comes to history and tradition.
