Every team is 'integral' except i suppose you could dismiss the bottom 3rd of each league, as things tend to work that way.
I'd hardly say it's 'easily' the best conference ever. 2007's and 2005's and 2004's ACC come to mind, and that's just one conference over the past 5 years. A solid case could be made for any of those over this year's big east, and with 5 and 4 and 7 less teams to wit.
Great, so Pitt and Uconn are stellar and lousville is showing some signs of life(though recent losses to ND and earlier slumps at Wky. aren't the stuff of dreams), and marquette's last 7 wins in 9 games have been against depaul, st johns, notre dame, georgetown and the apparently non-integral seton hall. There's a loss to mighty south florida somewhere in there too.
That measures at, what?, 2 great teams, 1 near-great team, and a decent 2 trailing.
UNC, Duke. Wake. Clemson, Florida State.
The distant is not so great as they'd like us to believe.
