         Re:      REGISTRATION STATEMENT ON FORM S-8

Ladies and Gentlemen:

         We have acted as counsel to SportsLine USA, Inc., a Delaware
corporation (the "Company"), and have reviewed the Company's Registration
Statement on Form S-8 covering 1,000,000 shares of the Company's authorized but
unissued common stock, $.01 par value per share (the "Common Stock"), issuable
pursuant to stock options granted pursuant to the Company's 1997 Incentive
Compensation Plan, as amended (the "Plan") . It is our opinion that shares of
Common Stock issuable under the Plan, when issued upon exercise of and in
accordance with the terms of stock options outstanding or to be granted under
the Plan, will be validly issued, fully paid and non-assessable.

         We hereby consent to the use of this opinion in the above referenced
Registration Statement. In giving such consent, we do not hereby admit that we
come within the category of persons whose consent is required under Section 7 of
the Securities Act of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission promulgated thereunder.

                          Very truly yours,

                          /S/ Greenberg Traurig Hoffman
