Today is National Signing Day, when high school athletes from fall sports make their official commitments to college teams.

While several high school seniors who play Olympic sports are signing as well, much of the emphasis for many schools is placed on football programs.

Locally, offensive lineman William Heine of East Chapel Hill has committed to Georgetown and Chapel Hill's R.J. Quick has signed on for Winston-Salem State.

Heine, a 6-5, 280-pound senior played at right tackle for East, helping to protect record-setting QB Drew Davis in coach  Bill Renner's "five-wide" offense. Heine will be joining his brother James at Georgetown, who's a pitcher for the Hoyas' baseball team.

Quick, not the biggest Tiger at  5-11, 180 pounds, was still one of the biggest guns as a top receiver for coach Issac Marsh as CHHS went 10-3 last season. He was also one of the quickest, no pun intended, with 4.5 speed.

The University of North Carolina is announcing its commitments — including Phil Williamson of Jordan — from the Class of 2012 this afternoon.
