As we saw vs UCLA, there are 3 ways to bust a zone: penetration & ball movement, 3ptrs, transition opps. KU used all to blow out a rebuilding royalty program.
I could postulate, that it was Coaching101 to leave a misfit (BG) at home, allowing team chemistry to shine, & the kids to play focused without wondering if BG is pissed about his touches or minutes...but I dont have to, since that is old news.
My main point is to see all the in-rhythm, openlook 3att's that Self didnt seem to have any issue with. In the flow of the offense, and hardly any as buzzer beaters. So in terms of 3% analytics and theory--> these are the best types of 3s to be shooting. Did Svi really have 11 3pt att's? Yes! And no quick yank? Graham, Selden, Perry, Svi, BG, Mason--> we got a ton of >38% 3pt shooters. Bragg may have a 3gun as well...
But my second point is that certain shooters always have had a "green light" on 3s: even from day 1. Rush, Sherron, Chalmers, Brady, Reed, Teahan, Greene, Frankamp (just couldnt hit em all season), Tyshawn, Elijah, Selby, Selden, Wiggins, Oubre, Morris Twins, and "developed" RussRob & Releford.
Self's point about "settling" for 3's at the expense of running the offense is where a game's trend can take you to the fool's gold concept: (team starts off hot from 3, then cools off, while opponent keeps chipping away and catches you, while your 3% with enough atts, will actually "regress to the mean (season avg %)".
So the "fool's gold" isnt a knock on the 3ball, but truly an in-game phenomenon where you may go to the well too many times in that game. He wants players to develop and be well-rounded. That's always been Self's m.o.--> take high talent h.s. scorers, & turn them into complete players, which makes his KU teams a threat from every position.
Look at the 3wing. Self says, until Wiggins came along years later, that Brandon Rush was his best wing player, and he was. Watched a freshman game of his, & he was everywhere on both ends of the court, defending, rebounding, shooting 3s from day 1. Andrew White couldnt do all that. Wiggins could. Releford got to where he could. XHenry was borderline at it, and Selden was sporadic. Selden likes the highlight pass, so we should commend his unselfishness, while we see if he develops that ptp'er mentality, in games we need him.
The corollary to the 3ball, is if you use it as a 'foundation' piece, you will live and die by it as IowaSt and Duke have repeatedly proven. Any team can get hot & go off from 3, & get surprise wins...but what happens? They regress to the mean...law of averages. Look at VCU's lone cinderella run, ya beat overall 1seed (ku)...a game that actually got Shaka the TX job (according to his own infamous comments this April), yet he's had trouble recreating his own success he had in 2011, hasnt he? They got to the final four and couldnt sustain their 3%, were overmatched, & got bounced. And we dont even need to discuss UNI, right? For Ben Jacobsen hasnt duplicated anything, as he now toils in the MVC shadow of Gregg Marshall, whose hard-nosed playstyle is from the same page as Self's. Gameflow, in-rhythm 3s. Same as KY: Cal gets p.o.'d when they start chukking too many 3 misses. Cal said they got away from "feeding Karl Anthony Towne", in their seadon-ending loss. Must have balance.
Recall the zone-busting 08 champs? 3s were an integral part of their "toolkit", but not their identity, like it is with IowaSt. Subtle difference?
Recall also those 08 champs, & how many ugly games they were able to win, when they only made 1-2 treys in the whole game? There have been KU wins with zero 3s made. The 2012 runner up Hawks are a good example of a team finding ways to win on cold shooting nights. They actually epitomized that in every tournament game, except the final one...a game and the type of opponent you need every gun you have, or you lose.
Final point: there is no "magic" number or balance on 3 att for Self: it depends how efficient a team is with it. Shooting good %? Keep working the O, but come back repeatedly to the 3--I mean you still should run offense to keep the opposing D guessing... But if your 3 goes cold...you'll have to rely on other elements of the offense, if you have developed them, wont you?
