PG—Mario Chalmers/Carlos Arroyo
SG—Dwyane Wade/James Jones/Eddie House
SF—LeBron James/Mike Miller/Shavlik Randolph
PF—Chris Bosh/Udonis Haslem
C—Joel Anthony/Zydrunas Ilgauskas/Juwan Howard/Jamaal Magloire/Dexter Pittman
While the Heat may be No.1 in a lot of lists, depth is not one of them. The reason for them to even be this high in this list is because of how talented their starting lineup itself is. However, let's look at the rest of the team as well.
At PG, the Heat's weakest position by far, they have third-year player Mario Chalmers and his backup, veteran Carlos Arroyo. The Heat better hope Wade and LeBron can do most of the ballhandling because Chalmers and Arroyo won't cut it.
At SG, the Heat have the talented All-Star guard Dwyane Wade and solid, sharpshooting backups in James Jones and Eddie House.
At SF is the two-time MVP LeBron James, backed up by three-point specialist, Mike Miller, and role player, Shavlik Randolph.
The PF position is solid as well with Chris Bosh starting and Udonis Haslem as his backup. However, there is no depth from there. At C, the Heat loaded up and have five serviceable big men in Joel Anthony, Big Z, Juwan Howard, Jamal Magloire, and rookie Dexter Pittman.
Need better point guards and centers.
The Heat have a weak starter but major depth at C, but lack everything at their other weak position of PG. Still, their lineup is talented enough to do major damage.
