Apparently, the Arizona Wildcats aren't the only ones who have "unfinished business" to take care of.

So do those Wildcats over in Lexington, according to what Aaron Harrison said when he and brother Andrew decided to return to Kentucky next season.

With a total of nine McDonald's All-Americans on its 2014-15 roster, Kentucky now could be the preseason No. 1 for 2014-15, although Arizona is still likely to be in the top three or four. Arizona will have three "Burger Boys" -- Brandon Ashley, Rondae Hollis-Jefferson and Stanley Johnson.

None other than Miles Simon likes Arizona's chances to win the Pac-12 and national title, however.

A lot of NBA decisions rolling in as the Sunday early entry deadline approaches will affect UA opponents next season:

-- Spencer Dinwiddie says he realizes NBA draft night might not be the "most glamorous" for him but he's leaving Colorado anyway. Draft Express has him going No. 47 in the June 26 draft.

Dinwiddie's decision should bump Colorado down to middle of the Pac-12 projections for next season (UA, UCLA, Stanford, Oregon and maybe even Utah could be picked ahead of the Buffs).

-- Mitch McGary will leave Michigan for the NBA rather than face a one-year suspension for testing positive for marijuana. That makes the Wolverines' frontcourt pretty young.

-- Khem Birch decided to leave UNLV for the draft even though he may not be picked in it.

More landmark events in the NCAA world:

-- Northwestern football players are voting on whether to unionize. A former walk-on player says the school is putting pressure on players to vote against it.

-- Power conferences could get more, well, power (which could give their schools yet another recruiting edge).

-- The NCAA is moving not to allow hardship transfers any immediate eligibility, but will expand the time clock so they can still get in four seasons (i.e. for somebody who transfers early, sits out, then transfers again, they will get a "six year clock" in order to get another redshirt year out that final season in.)

UA recruiting targets Ivan Rabb and Stephen Zimmerman will be on display this weekend in the EYBL event outside of Sacramento.

Herb Sendek picked up a third-team juco all-American.

Lorenzo Romar says his recruiting philosophy is changing, after waiting too long for some high-profile prospects to decide and missing out on others.

Ricky Kreklow is leaving Cal but says it's not because of the coaching change. He has a year to play as a grad student.
