Right now you have Clemson and maybe Virginia Tech and only Clemson is a definite top 10 team. The average teams and the bottom feeders in the current ACC are no better than the ones in the Big East we entered.
Cards first year in the B East only 3 teams had a winning record, and one of the three was 7-5 - the other two WVU and the Cards. Cards couldn't play themselves so their schedule in the Big East "they entered" as you say, was not that great. Only 2 ranked teams at the end of the year and the Cards were one of them.
WVU was the only team to win a bowl, the league went 1-3.
Right now the ACC isn't just Clemson and Va Tech. BC is also ranked and rising. Miami FL dropped a game to frickin LSU and is still ranked so I don't think their season is over yet.
NC St and SU might be getting better and Duke has a two TD win over Northwestern. They are a combined 8-0. No they are not powers by any stretch but not a horrible middling next tier, "right now".
NC St did win 9 games last year and finish the season ranked. So they may be turning a corner.
The league is down because FSU blows and the Cards do too.
And "right now" Clemson is a definite top 3 team according to the polls, not just a Top 10, so nice try framing that low ball on them to assist dragging down the league with your semantics game.
