Rodney Rice of St. John's, The Washington Post's high school basketball player of the year, signed a letter of intent with Boston College yesterday. Rice, a superb outside shooter who is 6 feet 3, averaged 20 points and seven rebounds in leading the Cadets to a 22-7 record.

Rice said he picked BC over George Washington, Richmond and Georgia Tech because of the Big East Conference school's overall athletic and academic program and style of play.

"Rodney felt he could fit in right away with Boston College," said Rodney Rice Sr., an all-Met at Fairmont Heights in 1960. "We sat down and discussed the advantages of each school and Rodney preferred BC."

Rice's teammate, Ronald Steptoe, was awarded an appointment to the U.S. Military Academy.

Other area players who have signed include McKinley's 6-3 Darren Campbell, with Rutgers, and 6-6 Kenny Simril, with Laredo (Tex.) Junior College.

Helene Baroody, The Post's female player of the year, and her W.T. Woodson teammate, Lorraine Rimson, will attend Auburn and Florida State, respectively. Other all-Met girls who have signed are West Springfield's Liza Lank, with Virginia; Wakefield's Kas Allen, with George Washington; Robinson's Kim Skala, with East Tennessee State, and T.C. Williams' Valorie Jeter and Traci Tate and Hayfield's Darlene Ford, with Winthrop (S.C.).

Nationally, signings include 7-foot Lyle Shannon of Towson (Md.) Catholic, with West Virginia; 6-6 Charles Rogers of Pickens, S.C., and Fork Union Military Academy, with Virginia Tech; 6-5 Antoine Joubert of Detroit, with Michigan; 6-5 Marty Simmons of Lawrenceville, Ind., 6-2 Steve Alford of New Castle, Ind., 6-8 Todd Meier of Oshkosh, Wis., and 6-7 Daryl Thomas of Indianapolis, all with Indiana.

Also, 6-5 Dennis Hopson of Toledo and 6-1 Curtis Wilson of Akron, with Ohio State; 6-6 Johnny Ford of Gary, Ind., and 6-8 Dave Snedeker of Springfield, Ill., with Iowa; 6-2 Darryl Johnson of East Lansing, Mich., and 6-7 Barry Fordham of Buffalo, with Michigan State; 6-6 Chris Berg of Arlington Heights, Ill., with Northwestern, and 6-10 Sylvester Kincheon, who verbally committed to Houston Tuesday, with Mississippi.

Also, Craig Wessel, a 7-footer from Elkhorn, Wis., with Wake Forest; 6-11 Ray Gromlowicz of Wilmington, N.C., and 5-11 Keith Williams of St. Albans, N.Y., with North Carolina-Charlotte, and 6-9 Charlie Simpson, the Colorado player of the year, with Southern California.

Contrary to previous reports, Kenny Hutchison of New York City has not signed with North Carolina State. The senior guard said he will make his decision when Jim Valvano decides whether he will remain as the Wolfpack's coach or take a job with the New Jersey Nets.
