The team has a ton of talent and it didn't look like Lebron in particular really tried too hard
That being said, I'll play devil's advocate:
Starters appeared tentative on offense. Tons of passing talent and you can see they were trying to figure out when to shoot because unlike last year you pass the ball and you likely are going to get a better shot. Not too concerned about this: too much talent and it's early in the season.
More concerning: Maccabi had good success by putting Kyrie and any non Andy 5 into pick and rolls. Thompson had nice block but he's not someone whose feared by a guy like Pargo and he took it the rack if he had a step on Kyrie. Haywood was just too slow to do much against the pick and roll. I think it's much safer to keep your best pick and roll defender in Andy with Irving and then protect Haywood/Thompson by pairing them with Delly
