It’s been a month and a half since Charter hired The Raine Group to sell Spectrum SportsNet, the Los Angeles cable home of the Lakers, and dozens of companies have seemingly expressed interest, from private equity firms to traditional media companies. Mark Walter, who recently became the team’s owner, has also shown openness to taking ownership of Spectrum SportsNet away from Charter, which doesn’t see a long-term play in keeping the R.S.N. in its portfolio. Now, the burden is on Raine to distinguish the real potential acquirers from those kicking the tires for their own gain—to learn about the economics of the business to fuel some other investment thesis, say, or just out of morbid grinfucking curiosity.
