Magic Johnson says he's not tuning in to HBO's new show about the "Showtime" Lakers, but the NBA legend should definitely reconsider -- so says "Winning Time" actress Caitlin O'Connor, who tells TMZ Sports he'd love the series!!
As we previously reported, the 5-time champ told us he was NOT looking forward to Adam McKay's project starring John C. Reilly ... pretty much distancing himself from the entire thing.
But O'Connor -- who plays legendary Laker fan Dyan Cannon in the series -- is hoping Magic changes his mind .
