Miami Heat receive advice from Floyd Mayweather Jr.

This offseason, the Miami Heat have seemingly done everything in their power in preparation to defend their championship next season, including receiving advice from a man who has never lost.

According to espn.com, the defending NBA champion Miami Heat received a visit from undefeated boxer Floyd Mayweather Jr. this Sunday.

According to NBA Finals MVP LeBron James, per ESPN:

"With him being 17 years-and-0 — we’re trying to defend two titles — he’s been defending for a long time. He definitely knows where we’re coming from. It’s definitely exciting to have someone, one of the greatest of all time, to be in your presence. It’s something you can talk about years from now when you look back on the history of sports. That guy was at our practice."

Indeed, Meyweather Jr. should know plenty about defending championships. The 36-year-old boxer is 45-0 in his career, has won titles in five different weight classes, and has eight championship belts. For a Heat team trying to become only the fourth team in NBA history to win three consecutive championships, there maybe no one better to learn from.

According to the report, Mayweather Jr. spoke to the team about the difficulties it will face staying on top against stiffer competition.

With the signing of young players Greg Oden and Michael Beasley, and the resigning of key contributors such as Chris Anderson, the Heat already seem to be doing what they can to stay on top. But a motivational speech from Mayweather Jr. surely couldn’t of hurt.
