John Beilein doesn't want to talk about it. Tom Izzo really doesn't care to, either. But in case there were any lingering doubts about Michigan's return to basketball relevance, coming off a shared Big Ten championship last year and back-to-back NCAA Tournament berths, now there's this: a No. 1 ranking in the Associated Press Top 25. It's the first for Michigan in 20 years, going all the way to December 1992, the opening weeks of the star-crossed Fab Five's sophomore season in Ann Arbor. It's just the fourth time in the AP poll's 64-year history that the Wolverines — 19-1 this season and off to the best start in school history — have held the top spot.
