Mark Bartelstein, Founder & CEO of Priority Sports (@PrioritySports) joins us to discuss his work with clients that range from NBA stars Gordon Hayward and Bradley Beal to NFL star Kirk Cousins (who just signed a landmark fully guaranteed FA deal with the Minnesota Vikings) to NFL HOF'er Kurt Warner and Golden State Warriors Head Coach Steve Kerr. Priority Sports led all agencies last summer with $354.6 million negotiated for nine different NBA players. Bartelstein discusses his agency, the upcoming summer of free agency in the NBA, whether or not Cousins' contract will pave the way for guaranteed NFL contracts in the future and offers his advice on how to conduct a successful negotiation. Blake Lawrence (@Blake_Lawrence), CEO of Opendorse (@Opendorse) also joins this week's show to discuss his company's innovative work with helping athletes build their brands on social media and then monetizing their social media platforms. Opendorse has deals with the NFLPA and LPGA amongst others to assist athletes. Follow us on Twitter @SBRadio and on Instagram @SportsBusinessRadio.
