I've been following Markkanen pretty closely - he was friends with my son, they were classmsmates at school and used to play football (soccer) in our yard and basketball at theirs. A quiet, well-mannered kid.
I think he is getting his old NBA-self back. With the Bulls, something went wrong, he bulked too much, lost quickness, agility and footspeed. Then the Bulls pretty much made him stand in the corner - and I don't mean to put the blame to the Bulls org, he was lumbering out there.
I remember putting out the thought that Markkanen is not a PF/C, but a versatile F, who could play both forward spots. I was told no, too slow, lacks lateral quickness, can't create his own shots, handle not good enough. Then he went to the Cavs, and did just fine as a small forward.
This is my hot take after two games: you may be getting the best version of Markkanen so far. LM has never looked as complete as a player as he has now - except for one month with the Bulls, still remembered as "Februlauri". So bear in mind he has been streaky, both as a shooter and as a whole.
And finally "Lauri" is pronounced just like "Lowry"

From the basketball's perspective, travel is a nice pause from being pounded to the floor.
