It’s round two in the high-stakes real estate ring for Sugar Ray Leonard. The long-retired five-time world champ, now 65, gave it an unsuccessful go about two years ago amid a tidal wave of publicity and a too aggressive asking price just shy of $52 million. Now, the legendary boxer has hung a considerably lower if still startling $46.5 million price tag on his longtime estate in the Riviera, a particularly pricey neighborhood of L.A.’s posh Pacific Palisades community.
