PROVO, Utah — Noah Hartsock can brag that he once blocked NBA All-Star Blake Griffin. And the Brigham Young senior soon might be able to say he recorded more blocks for the Cougars than 7-foot-6 Shawn Bradley.

Yet the 6-8 forward with the thinning hair and "aw-shucks" personality knows not to go overboard.

The Griffin block happened in high school, and Hartsock points out that Bradley needed only one year, not four, for his 177 blocks.

With 52 blocks this season and 174 in his career, Hartsock must come up big again when BYU (25-8) faces fellow No. 14 seed Iona (25-7) Tuesday in Dayton as part of the NCAA tournament's First Four games. The winner will face No. 3 Marquette on Thursday in Louisville in the East region.
