As a Los Angeleno who happened to be a freshman in high school the year the Lakers drafted Magic, I’ve been pretty fortunate as a fan:
Lakers (1979), 10*: 1980, 1982, 1985, 1987, 1988, 2000, 2001, 2002, 2009, 2010
Dodgers (1972-ish) 2: 1981, 1988, 2017 (heh-heh-heh)
USC Football (1972) 5: 1972, 1974, 1978, 2003, 2004 (Eff the NCAA; I’m not giving back the 2004 title)
Rams (1972)1 (sticky): 1999. The Rams were pretty much dead to me when they relocated to St. Louis, but the laundry – and the high-powered offense – eventually got to me. But if someone claimed I don’t deserve to claim that one as mine, I wouldn’t argue.
*Thank you, New Orleans Jazz, for signing Gail Goodrich as a free agent and thus giving up your 1st rounder as compensation – yes, that’s how the Lakers got the rights to Magic Johnson)
