Not sure what your definition of "overrated" is but the Big East will be lucky to keep 3 teams in the top 25 all year (I would be ecstatic if that were the case) never mind a 4th team. Their strength of schedule is simply too weak to justify.
- Creighton has Drake and Arkansas left along with their 3 good wins already plus a veteran team that had a great run last year.
- Villanova has a star in Maddie but frankly will need to impress against Iowa State when that game comes up as their OOC is kind of weak. Playing the Philly 5 does not help them anymore and is antiquated (sorry all the nostalgia loving crowd).
- As for Marquette, a win or very good game today and a win over Colorado would aid their situation as well as a strong Big East Season.
But take a look at the rest of the P5, my assessment is maybe the PAC12 or Big10 are having down years, the rest of them all dwarf the Big East contingent.
PAC12 with Stanford, Utah and UCLA as the top 3 but Arizona and Oregon have more talent than all but UConn and Creighton. So 5 teams will be in the Ranking consideration all year.
The Big 10 has tOSU, Indiana, Maryland, Iowa and Nebraska (despite their loss to Creighton) who should be in the Ranking consideration all year and the first 4 easily in the top 16.
Big12 has Iowa State, Oklahoma, Baylor, Kansas State and the much-maligned Texas.
ACC is also down this year from an "elite team perspective" but ND (ND could force itself into a top 8 consideration), Louisville, NC, NC State, Duke and VPI are all much stronger than what the Big East can put on floor.
The SEC is stacked as usual with SC, LSU, Georgia, Arkansas, Ole Miss, Tennessee and heck even Alabama could make noise.
I am willing to see and read where you think the rest of the P5 is weak when compared to the Big East so please show us.
