LeBron James soft? He is criticized by NFL player Jonathan Martin

But the Miami star took heat on social media today after exiting early because of cramps in the Heat’s 110-95 loss to San Antonio in Game 1 of the NBA Finals.

Former Miami Dolphins offensive tackle Jonathan Martin — the victim of the team’s bullying scandal last season — was one of the first to weigh in.

On Twitter, @J_Martin71 said: “With that said … C’mon bruh. Drink a Gatorade and get out there.”

Martin, who now plays for the San Francisco 49ers, sent that tweet at 11:36 p.m. — before the game had ended — and later deleted it.

The game was played in a sweltering arena in San Antonio because the air conditioning failed.

Gatorade also took a shot at James, an endorser of Powerade.

@Gatorade said on Twitter:

It’s likely that this will be Topic A on all ESPN programming today. It’s a perfect launching point for a Skip Bayless-Stephen A. Smith debate on LeBron vs. Jordan.

After all, one of Michael Jordan’s most famous performances came when he was ill with the flu. That was on June 11, 1997. As the story goes, he was so sick — it might have been food poisoning, from a bad pizza — that he didn’t get out of bed until 70 minutes before Game 5 of the Chicago Bulls’ championship series against the Jazz.

But he made it to the arena in Salt Lake City and scored 38 points in a 90-88 victory that gave the Bulls a 3-2 lead in the series that they wrapped up two days later.

James did have some of the Twitterati defending him, too.
