Call it some sort of kismet when it comes to Dan Beckerman, chief executive of downtown-based AEG, and Peter Guber, boss of Mandalay Entertainment Group in Culver City. Beckerman was a student in Guber’s sports business class at UCLA’s Anderson School 25 years ago. He impressed the teacher, kept in touch, and eventually began teaching the course with him – a shared duty the duo continues. … Beckerman went on to the Clippers, and then to AEG and its stable of sports franchises and venues, while Guber added stakes in the NBA champion Golden State Warriors and Dodgers over the years. That gave the pair of professors a point of contention, since AEG owns a piece of the Lakers – and the rivalry will soon add a layer thanks to Guber’s stake in the Los Angeles Football Club, which is expected to start competing with the AEG-owned Major League Soccer franchise L.A. Galaxy, and has a home stadium currently under construction in Exposition Park and named for Banc of California. … Beckerman has some common ground with another rival from the LAFC ownership roster. Turns out he and Will Ferrell both grew up in Irvine. … Sonny Astani is familiar with the challenges that come a long way from master-planned Irvine, and that helps him thrive on inner-city development, as the item in our Real Estate column on page 30 shows. He’s particularly familiar with the challenges that come with the beyond-dense scenes of street peddlers, shoppers and the rest of the crowds that regularly overwhelm sidewalks and spill into the streets around the swap meet rooted at the Westlake Theatre building at Wilshire Boulevard and Alvarado Street, across from MacArthur Park. Astani learns the neighborhoods he works, though, and a recent find at the swap meet makes the messiness OK with him. “Someone told me about a ‘genius chiropractor’ at the swap meet, and he also does acupuncture – for 30 bucks my neck feels about 10 times better,” Astani says. No wonder he’s considering another buy in the neighborhood after cashing out on WilshireValencia. … Anyone else notice that some of those day spas that dot the landscape between downtown and Koreatown are renting futons and rooms at less than $50 a night – and drawing young business travelers who pocket the difference on their lodging per diem? … Sullivan Says: Go for the ribs but don’t miss the stewed tomatoes at Baby Blues in West Hollywood.
