Luka had a 37.1 % usage rate in his first playoff. He did over 40 in the next two playoffs. He was incredible all 3 years but needed a lot of luck* to get to 2-2 on his playoff series record and reach his first conference final.
Now, he's wounded, inefficient, with a usage rate at just 31.3%. and this is the scariest playoff team the Mavs have had.
Team ball is just better.
*Role players shot the mfkn lights out and Suns got hit with Covid. Hell, he got out of the first round going 2-2 (his team won 2 games without him).
