Cohan attended Arizona State University and is an avid golfer.
In May 2007, Cohan was reported to be fighting a $160 million dollar tax case in federal court over claims that he evaded taxes when he sold Sonic Communications in 1998 for more than $200 million.
In May 2009, an unnamed writer in Sports Illustrated reported what was in their opinion the top ten best and worst owners of basketball teams, ranking Cohan as their 4th "worst" owner. The writer criticized Cohan for sticking with Don Nelson as the Warriors' head coach and for some generally poor team performance, apart from the 2007 playoffs series win against the first-seeded Dallas Mavericks. The editorial claimed that the team appeared to be repeatedly rebuilding.
In July 2010, the Warriors were sold to Peter Guber and Joe Lacob for $450 million
