Following the recommendations here to poach the Grizzlies' assistant coach, I did a deep dive on them.
I did not realize their head coach (Taylor Jenkins) interned with the Spurs, was head coach of the Austin Toros, and even had some overlap along with Quin Snyder there. Then, he was assistant coach to Mike Budenholzer in Atlanta and even followed him to Milwaukee.
I could definitely be wrong (since I'm getting most of my info from Google) and please correct me if I am, but it seems coach Bud uses a "5-Out" offense. When Coach Jenkins went to Memphis, he brought in Noah La Roche (who's been running the "Read & React" offense since 2006) and EuroCup Coach of the Year: Tuomas Lisalo (who runs a "Read & React" clinic).
Lisalo incorporated Coach Pop's "0.5" Basketball into his system.
When Lisalo came to the Grizzlies, Tiago Splitter took over the Paris team with similar success (keeping the same system).
I don't want Coach Bud, but I am intrigued about these coaches running the "Read & React" offense (La Roche, Lisalo, and Splitter).
