let's assume, for the moment, that luke is in this job "for the money" and will do whatever he is told to do, with regards to winning and losing.
(and i don't mean "throwing games" - i mean "playing combinations that aren't going to work against that night's opponent")
you can't expect players to "tank" - but the coach can control that by who (and WITH whom) he puts on the floor as a unit.
"tanking" can also be "player development".
for instance, neither buddy nor bagley should have played much after the first quarter - neither was effective.
quarter number two could have/should have been a time to play the young guys - but that wasn't done.
when guys have as brutal a first quarter/first half as buddy/bags, you simply (as a coach) have to recognize that "this isn't your night, kid" and play someone else, especially when the outcome is a foregone conclusion.
(unless the staff has already concluded that the new young guys are not long term nba players, just "roster fillers".
there is also a second way to proceed and that is to tell the two players who are playing the worst (and last night, it was buddy and baggy) that if they want to continue for the remaining three quarters (last night), they need to have one specific goal, one thing to "work on" (over and over and over).
buddy: either use the rest of the game to work on driving to the basket and cease shooting three's (for this one game) or take a seat.
bagley: if the intention was to allow him to work on his post-up moves against real competition, ok, live with that.
but a better solution regarding bagley is to say, "you need to do one thing and do it until you are good at it - then move to something else" and in bagley's case, start with his strength: which is (say it with me now) REBOUNDING.
bagley has a nose for the ball and one of the quickest second jumps in the league.
i don't know if today's players even know who dennis rodman was, let alone moses malone.
give bags some video to watch and bring in a big man who has actually played the game successfully to discuss rebounding with him (since we know he has some natural ability there). otis thorpe sat in my row when the kings closed arco and honored past players. guy has a ring and is a good guy. bring him in as a "one player coach". if bags can't learn something from him, then he just isn't teachable. i'd say, "bring in rodman" but that is always an explosion waiting for detonation, but at least watch some film of him.
marvin bagley could lead the league in rebounding if he focused solely on that (as rodman did). maybe someone in the FO has to tell him, we will pay you big money if you show us a skill that you excel in - and more once you take on new skills (next: p/r)
but start with one skill. ALL he should be focused on is grabbing every rebound. if he has an easy putback, take it, but mostly just grab the board and toss it out to a guard (we have enough shooters). baggy may not even know that rodman has rings and was once paid 6 million a year to do NOTHING but rebound (probably equals 15-20 mil today).
guys want to score, because they think "that's where the money is", but that's not the ONLY place the money is.
bagley COULD start out as a one dimensional rodman type and develop into a moses malone type - there is plenty of time.
a good coach puts his players in a position to succeed.
asking bags to be a well rounded machine at this point is pointless - he can't do it and his confidence will soon be shot.
give him one thing to "be the best" at and ask him to work on his offensive moves in practice, not (yet) in games.
assure him that, "if you board, you play" (and "get paid").
otherwise, he is a wasted draft pick.
same with buddy.
