Despite publicly saying they see “no hurdles” in dealing with the Raiders, UNLV officials hired a lawyer versed in knocking them down after seeing the team’s first offer. UNLV responded to the team-friendly proposal last week by retaining attorney Daniel Etna of Herrick Feinstein LLP, a high-priced titan in sports law, to advise the university in negotiations. The agreement between Herrick and the university can extend up to two years, though talks with the Raiders likely need to wrap in the next few weeks. Etna’s services will cost UNLV $745 per hour. Other work from New York-based Herrick will cost less, starting with a rate of $280 per hour for paralegal services and ranging up to Etna’s fee. Those rates could total a significant expenditure for the university for a negotiation in which Sam Boyd Stadium executive director Mike Newcomb said he sees “no hurdles” at last week’s Las Vegas Stadium Authority board meeting. UNLV spokesman Tony Allen confirmed the details of Herrick’s arrangement. Allen also said local attorneys with Snell & Wilmer are consulting with university officials on the agreement, and that their work began while the firm was being retained for unrelated real estate matters. Financial details of Snell & Wilmer’s arrangement were not immediately available. “Analysis and negotiation of the draft joint-use agreement is ongoing,” Allen said. “We look forward to working with the Raiders and the Stadium Authority Board to give UNLV football — and our great fans — access to a stadium and accompanying game-day experience that will rival the best in college football.” University Regent and attorney Trevor Hayes backed the Herrick contract as insurance for UNLV’s long-term interests.
