As for the Big East this season, there is no question St. John's and Seton Hall are certainly not as good as they have been in the past. Considering St. John's and Seton Hall are usually two of the better teams in the Big East, this is certainly a disappointment. On the other hand, while I would hardly call Villanova and Georgetown great teams, they are both doing better this season than they normally do. Both those schools are usually at the back end of the Big East standings and the RPI for that matter, but that is not the case at least for this season.
While Big East teams generally had a horrible start to this season, it seems to me that conference teams have picked it up some and are not quite as bad as everyone makes them out to be. Still, even with saying that, the Big East is hardly a big threat at this point to have multiple teams make the NCAA Tournament with any sort of consistency.
As for scheduling, from listening to Chris Jones during the broadcast of UConn baseball game, it seems that scheduling for upcoming seasons starts a few years in advance. Obviously, tinkering with the schedule keeps on going up until the schedule for a coming season gets released.
