1. Duke's Jahlil Okafor is going to remind people of Tim Duncan.

I'm not saying Okafor is going to be Tim Duncan because that wouldn't be fair. Duncan is one of the best big men to ever basketball at any level, but Okafor is going to be the best pure center that the college game has seen in quite some time.

The 6-foot-10 Okafor is a throwback. In a time where fewer true five-men are playing the game and the position is filled with shot blockers or power forwards masquerading as centers, Okafor is like a mid-1990s NBA big man with post moves, craftiness and incredibly long arms. The Chicago native is the type of jaw-dropping talent that comes along once every couple of a decades.

Okafor had 29 points and nine rebounds in last week's Jordan Brand Classic at the Barclays Center and looked like the clear favorite to be the top overall pick in the 2015 NBA Draft. It may sound crazy to make that type of prognostication before Okafor ever plays a college game at Duke, but watch him play once and you'll get the point.

Duncan stayed four years at Wake Forest and was dominant by his junior season after being somewhat raw as a freshman and sophomore. That won't happen with Okafor. This kid is primed to make a major impact from the first day he steps foot in Durham.

2. Chris Obeka's return to St. John's makes the Red Storm a legitimate contender in the Big East.

The 6-9 Obeka took a step back as a sophomore (2.9 blocks) after averaging 4.0 blocks as a freshman and now Obekpa's decision to return to Steve Lavin's program for his junior season makes St. John's -- at least on paper -- the biggest challenger to Villanova in the Big East next season.

The Red Storm will return a veteran perimeter of Rysheed Jordan, Phil Greene and D'Angelo Harrison plus a savvy fourth guard in veteran Jamal Branch. St. John's also has the premier shot blocker in college basketball manning the pivot in Obekpa and Dom Pointer could be primed for a breakout season up front at power forward.

The Red Storm have been a different team over the past two years when the 6-5 Pointer (5.9 points, 3.2 rebounds last season) has played expanded minutes at power forward and he should now have that type of opportunity next season with the departure of JaKarr Sampson, who left St. John's early for the NBA. The Red Storm narrowly missed the NCAA Tournament last year but should be in position to challenge for a bid in 2015 thanks to a returning core that features multiple years of collegiate experience.
