Luka is really good in transition. I think it's his 2nd best attribute next to his PnR play.
Transition skills are at the bottom of my list when it comes to skills I want to see out of a basketball player. Fox has great end to end speed but you only see it about once a game. That elite skill nets him 2 points a game. Meanwhile he was next to worthless in the half court.
Dreaming about a bunch of up and down the court transition points to improve the team will wind up being a losing proposition. The overwhelming majority of points are scored in the half court and if that's not the bread and butter if your top players, then you aren't winning basketball games. Defenses are too adept to stopping transition points to make it a worthwhile skill to draft a guy on.
Wingspan means a lot more to a big man than it does a guard. That big man is supposed to be the last line of defense if the guard can't stay in front of his man. If Bagley plays the 5, it's going to be a layup drill for opposing offenses. The longer wingspan not only blocks and alters shots, but it allows the player to defend without putting themselves in a position to foul. Bagley will be forced to use his leaping ability to block shots and that's going to put opposing offenses on the free throw line quite a bit. Now if Bagley plays the 4, you have to match him up with the perfect 5 or else you're going to give up something on the offensive end and/or the defensive end. I don't like players that need to play next to a specific type of player in order to be successful. It's a difficult way to build a team.
One thing I like about Bagley is that he seems like the kind of guy who is going to put in the work. I'll take a guy who doesn't know how to play defense over a guy who can play defense but chooses not to. You can teach an eager player the skills to play D but you can't force someone to do it who doesn't want to. By all accounts, Bagley is a nice mixture of skill and bring your lunch pail to work kind of guy. Which is why I like him as the 2nd choice to Doncic. If he can't play defense it won't be for lack of trying and that's something I can't really complain about. He's not going to be lazy or disinterested in the game but it is very worrisome that his defensive awareness is the absolute polar opposite of his offensive awareness.
