Professional sports are serious business and after months, sometimes years of preparation, athletes treat winning and losing like life and death.

Especially in finals and championship deciding matches, things can get a little heated.

But no matter what the competition, these 15 athletes shouldn’t have been such bad losers!

1. LeBron James

He may be one of the most talented basketball players of his generation but LeBron proved he can be a really bad loser in 2009.

When his Cleveland Cavaliers lost to Orlando Magic in the 2009 NBA Eastern Conference finals, he not only walked off without shaking hands but also skipped the post-game presser.

2. Chris Bosh

Bosh is another NBA star to have acted ‘like a baby’, after his team’s loss in the 2011 NBA Finals, the Heat power fell to his knees and cried.

He saw criticism for his outburst and for showing emotion.
