Chris Bosh's health scare in which he missed the second half of the season with blood clots on his lung has triggered a renewed passion for the sport.

Bosh expects to be 100 percent ready by the start of training camp.

"That's renewed my passion," Bosh said at halftime of the Heat's 101-69 summer-league loss to the Boston Celtics at Cox Pavilion on the UNLV campus, where he watched as a spectator. "You don't miss anything until it's gone. It’s good for me to miss the game right now."

Bosh is still taking blood-thinning medication for at least a couple more weeks. 

"It's a little bit tougher getting back on that court if you haven't played in a while," said Bosh, who has been conditioning the past month. "I'm kind of working through that. It's good to get it out now as opposed to later. I feel good. Shot feels good. The conditioning is coming along."

Bosh is excited to finally have a chance to play with Goran Dragic.

"It will take some time," Bosh said. "We're going to have to figure out our roles and everything. It's just going to be a constant conversation.

"Pick and roll is going to be huge. I love a guard that attacks. That's always good for me. With chemistry, that's something that we’re going to have to get on the same page."
