Outside shooting and D are areas of weakness, but depth will make up for that.
If Lue splits minutes effectively to keep players fresh, you're gonna see shooters (Korver, Frye, Smith, Green, Crowder) and defenders (Shump, Smith?, Green?, Crowder) subbing in to help in game specific scenarios.
Lue has 15 guys to use like a Swiss Army knife. Crowder and Green, I believe, will be massively useful for helping LeBron on the wing, keeping him fresh.
IT, Rose, Wade can push the offense with second units, and Love remains a big #2 scoring option behind LeBron.
Calderon, Jefferson and some others may need to be cut. Pretty interesting overall if you ask me.
