I can't pinpoint when it happened but at some point this year Lowry checked out mentally.
At the start of the year, he was driving, shooting, going for steals, bodying up his man, grabbing rebounds and consistently being a pest. Now, it's like he's allergic to scoring and is going through the motions on defense.
I don't know what's going on but he is not performing anywhere near the level they need him to be at. His stats are pretty much at his career numbers but the overall performance, night-to-night, doesn't merit much enthusiasm.
We'll see. Next year is a contract year and players always show up for those. Of course, Colangelo will likley give him a 4-year extension to wipe out any motivation he has....
