Revrat is correct in that the conferences are still in a state of flux and that if his hypothetical event happens, the SEC raids the ACC, the NBE could end up a stronger conference. At this moment in time that is an extreme long shot. But events constantly change and listing the hypothetical possibilities, even if they are long shots are valuable for long term planning.
After the BE regular season in men's bb last season, in which UConn was 9-9 and lost 4 out of 5 and 5 out of 8, no one was giving UConn a chance to win the NCAA's. But the five game BE tournament win streak changed the perspective of viewers and players alike. There are twists and turns to events, some twists with higher predictability than others.
After the 2003 raid by the ACC, the BE was supposed to be dead. That didn't happen and the BE regained enough status to be equal to the ACC if not marginally better.
So we can't count out a raid on the ACC by the SEC or the B!G for that matter, and depending what happens with the BE, and what type of raid might take place in the ACC, the NBE can leapfrog the ACC in being a stronger conference.
