LB, the point isn't whether DJ is a valuable player, it's how they deal with his defensive liability.
Other than IH they have not covered his deficiencies very well. How they normally do it is DJ will normally score more and at a higher percentage then the front court will allow with him there. Of course that wasn't always true as you mentioned with Griffin.
Adelaide COULD play good team defence, a la with Shorter and Childress year, but revert to their old selves shortly after.
Do we have a better team this year than last year on paper? Yes, I think so when we are talking players 1-8 (McCarron, Hannahs, Withers, DJ, Humphries, Dech, King, Duffelmeier)
With just 4K McCarron, King and Duffel, the Sixers have improved remarkably from last season. No longer will we need Brandon Paul to bail us out or go to Jeremy Kendle or Daniel Dillon.
Bring in fully fit IH and this team is playoffs bound based on the imports being at least average imports.
I understand being apprehensive about the wait and see approach, but if they can get the timing right it could be very useful.
The Sixers you dislike is the umming and arhhing type where they move from Adris DeLeon too late or they double down on Ebi Ere.
Hopefully JVG is better than that given he actually has skin in the game.
