Here’s ESPN Miami reporting on the Heat, who begin their first round playoff series against the Charlotte Bobcats on Sunday:

Having finished 54-28, the Heat endured their lowest winning percentage of any season since James, Dwyane Wade and Chris Bosh came together in 2010. They’ve survived a seven-month grind during which nagging injuries forced Wade out of the lineup for 28 games and coach Erik Spoelstra to sort through 21 different starting lineups to fill the voids.

Now, the two-time defending champions enter the playoffs older — six of their top nine players are in their 30s — and arguably more vulnerable than they’ve been at any point. In addition to those factors, Miami limped into the postseason having lost 14 of their final 25 regular-season games and failed to secure home-court advantage throughout the playoffs, which proved to be essential last season.

Yet as defiant as they’ve ever been, the Heat insist none of those potential warning signs matter.

“On the outside, there’s more doubt,” said forward Udonis Haslem, who along with Wade are the lone players who have been with the Heat since their first championship season in 2006. “Within here, we’re still confident in one another. We still know what we can do. We still understand what needs to be done and we know how to get it done. From the outside looking in, people might have a different opinion.”
