The problems with the Heat are the same as they always were. Riley did an atrocious job filling out the roster after the Not Yet Big 3. Compare the starting 5 to the Celtics championship year. KG then was clearly better than Bosh but you'd have to give the nod to Wade and LeBron over Ray and Pierce. Now look at the other two.
Rondo 07-08
10.6 points, 5.1 assists, 4.2 rebounds, 1.7 steals, 49% from the field
Mario Chalmers this season
9.9 points, 3.4 assists, 2.7 rebounds, 1.5 steals, 46% from the field
Perk 07-08
6.9 points, 6.1 rebounds, 1.5 blocks, 61% from the field
Joel Anthony this season
3.2 points, 4.1 rebounds, 1.4 blocks, 53% from the field.
Chalmers is clearly a step below what Rondo was that year and Anthony is at least two steps below 07-08 Perk. Then consider that Miami's best three bench players are two unathletic wings and a severely undersized power forward. As good as the Heat can look, this is a team with massive weaknesses.
