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 500,000 shares of the Company's authorized but unissued common
stock, $.01 par value (the "Common Stock"), issuable pursuant to stock options
granted pursuant to the Company's 1997 Employee Stock Purchase Plan (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 thereby 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
                                                 Lipoff Rosen & Quentel, P.A.
