Luka has yet to hit the/his wall ............ sobrang meteoric ang rise ni Luka, he's bound to somehow stagnate at some point.
The wall can be anything or a combination of opposing defenses catching up, the law-of-averages catching up & injuries. It can happen this season, maybe not.
Last season we saw games, wherein players were targeting Luka - trying to rough him up.
It's the rite of passage of all great players - si MJ mala-fraternity hazing ang dinaanan with the PISTONS, KNICKS, CELTICS before he went super-saiyan.
It was very wise and strategic for Donnie Nelson to surround Luka with defensive-minded, rough dudes - former HEAT players Josh Richardson & James Johnson fit the bill.
James Johnson has the respect of everyone in the NBA - no one will be stupid enough to tangle with him, being an MMA/Boxing expert.
