Four Fearsome Lineups
(1) Chalmers + Wade + Bron + Bosh + J.Anthony
(2) Wade + Bron + Miller + Bosh + J.Anthony
(3) Chalmers + Wade + Miller + Bron + Bosh
(4) Wade + FA Signing (eg Raja Bell) + Miller + Bron + Bosh
The ability to go to any of those highly effective lineups and either create or eliminate matchup advantages against opponents is extremely valuable. That lineup flexibility is a huge plus in Miami's favour.
I'd substitute Shaq or Big Z for Joel Anthony, but yeah.
Don't underestimate the value of Joel Anthony here.
Joel Anthony is a good all-round defender. He defends very well in transition and in pick and roll situations. He has good anticipation and makes quality defensive rotations. He also provides solid shot blocking around the rim. Is a solid man-to-man defender.
Then add in his athleticism which is a great fit for the Heat. He has the size to defend centers (undersized but big enough to compete) but also the quickness to defend many power forwards around the league. That flexibility allows Miami to put Bosh on either big man depending on how they want to use Bosh defensively (which is a plus because Bosh normally doesn't do well against physical players and his help defense at the center position is good to very good). Bosh is best off defensively alongside an interchangeable big man, someone who can cover either big man position, which Anthony can.
Finally, offensively, Anthony does not need the ball so it'll be easier for Miami to manage touches between their star players. His value offensively will be as a screen setter (on and off the ball) and as a weakside offensive rebounder. Anthony will not clog up the paint so it'll be wide open for slashers like Wade and Bron as well as Bosh's driving game. Furthermore, Anthony is very quick for a center and he'll be another weapon in Miami's transition game.
I don't think much of Joel Anthony as an individual player but the fit here is very good for him. He'll be a nice role player ... a guy who helps the other four players play better.
------------------------------------------------------------
Miami should avoid a center like Shaquille O'Neal or Zydrunas Ilgaukas.
They will make their starting lineup weaker. Their lack of quickness, Shaq's need for the ball and clogging of the paint, their vulnerability defensively.
Miami are better off with a player like Anthony who can supply above average defense + will stay in the background offensively + will facilitate a running game.
If Miami signs a player like Shaq, they should use him as a bench player. He can make a positive contribution there.
-----------------------------------------------
Final Note -- Miami went 13-3 and in the 16 games that Joel Anthony started while Jermaine O'Neal was out injured last season.
Anthony is a good glue guy if you can surround him with enough offense and rebounding ... which Miami clearly can with Bosh, Wade and LeBron.
