It seems like North Carolina has a frontcourt player make a significant breakthrough each year. Last season, it was Brice Johnson. This season, so far, it's Isaiah Hicks.

The 6-foot-9 forward averaged 1.2 points as a freshman, 6.6 as a sophomore and 8.9 as a junior. Nothing special. But he's now averaging 15.0 points and 5.0 rebounds as a senior after getting 22 points and six rebounds in Monday night's 104-61 victory over Chaminade in UNC's Maui Invitational opener. Hicks is shooting a career-high 66.0 percent from the field and a career-high 76.5 percent from the free-throw line. He's among the main reasons why Roy Williams' Tar Heels are 5-0 with an average margin of victory of 28.8 points heading into Tuesday night's game against Brad Underwood's Oklahoma State Cowboys.

UNC is No. 7 in the updated CBS Sports Top 25 (and one).
