The Grizzlies' first day of practice did not involve full-court play, with Hansen showcasing more of his three-point shooting and defense.
Defense goes without saying; it's what the Grizzlies need most.
Even if Hansen had not showcased it, the coaching staff of the Grizzlies would have examined it closely, seeing as he was the only player on the team with outstanding defensive credentials.
As for three-point shooting, that was where Hansen was cutting corners.
The Grizzlies' tactics revolved around inside play, what was most needed?
Space.
A low post one-on-one in the paint was the easiest to defend against with a collapse.
And to have space, naturally you need three-point shots.
Unfortunately, Hansen found none of the Grizzlies' three-point shooters reliable.
At this time, whether it was Guy or Conley, their three-pointers were just "usable," not strong enough to support the strategy.
