I will say this again: it is a very long season.
This^.
A thousand times, this.
I know it's a long season and I still have faith in the Nets but not Garnett, he looks horrendous out there. Imagine what he'll look like 75 games from now....yikes.
I suspect that, assuming he is healthy, that he'll look just fine.
Garnett's main problem right now is simply that his trademark mid-long jumper is simply not falling. He's shooting an uncharacteristic 32.1% from the field when he is normally solidly over 50%.
In particular, in the 16-23 foot range across the top of the key, from elbow-to-elbow, historically he is a machine, hitting that at just under 50% (WAY above league average). That's where he smartly takes a big share of his shots.
This year, with Lopez to attack inside, it makes even more sense for KG to use that long jumper to help stretch defenses. So he's taken 25 of his 53 shots so far this year (almost half) from that range. But so far, he is just 9 of 25 (36%) from that range.
These are incredibly tiny sample sizes and will almost certainly swing differently as the season progresses. KG's form looks good and eventually those shots will start to fall again.
Six games and just 53 shots is a blink compared to a season. Check back on his FG% in another couple of weeks and this will all probably start to look moot.
