Chris Bosh is happy he doesn’t have to guard Chris Bosh.

Or LeBron James. Or Dwyane Wade.

“I wouldn’t want to play us,’’ Bosh said of the Miami Heat’s Big Three. “I’m glad I don’t have to play us.’’

When their trio of stars is on, the Heat are nearly unbeatable. That certainly was the case in Thursday’s Game 4 of the NBA Finals against the San Antonio Spurs.

James, Wade and Bosh combined for 85 points and 30 rebounds in a 109-93 win. It was easily their best combined outing this postseason.

So entering Sunday’s Game 5 at the AT&T Center, the thinking from the Spurs is simple. They’re just hoping the three don’t play like that again.

“You have to be close to perfect to beat them,’’ San Antonio guard Manu Ginobili said of when Miami’s Big Three is on like that. “If they’re having an OK game, we can make a few mistakes here and there and we can mask it. But when they’re playing like that, we just can’t make mistakes.’’

The good news for the Spurs is the trio hasn’t been playing like that regularly this postseason. James usually has been at the top of his game, although he did have his share of struggles in the first three games of the Finals.

Wade has been hampered by a painful bone bruise on his right knee. And Bosh has been up and down during the playoffs.

So one big question entering Sunday is: Can Miami’s Big Three keep it up?

“That Game (4) and stuff like that was the reason we came together,’’ Wade said of three joining forces in the summer of 2010. “It was good to see. ... That’s what we envisioned. It’s not easy to do that every night, but hopefully with three games left, hopefully we can be more consistent.’’

If that consistency continues by the Big Three, the Spurs might want to forget about winning a fifth championship in 15 years. If not, they have a chance.

Of course, it would help if San Antonio’s Big Three can get untracked. Tim Duncan, Tony Parker and Ginobili all have had issues during these Finals.
