Ok, looking for opinions on the following shot! IMO it looks aweful.

Details as follows...

Nikon D850

Nikkor 70-200mm F2.8

Nikon 2x Converter

 

1/1250sec  f5.6  iso500  @ 400mm

 

What is wrong here with the image. Despite the fact the photographer is amateur?

 

- That is original no edits shot jpeg

- That is a 100% crop.

 

Be glad of all comments

What is happening i'm not too sure, so all comments welcome.

Could just be softness caused by shooting wide-open and with the TC.  I'd expect better results when stopped down slightly.  Could also be due to it being ever so slightly OOF.

When using top of the line gear and not experiencing proper 
results is frustrating for sure. 

Have you considered…

1, performing an AF Fine Tune procedure without the TC and
   then with it?

2, I tried using TC's but gave up as they can only offer ques-
    tionable performance.

Perhaps the camera selected a focus point that wasn't the bird.  If so there will be some point in the image that is perfectly focused.  I don't think it is camera movement at 1/1250 but if it was hand-held that is certainly something to consider if there are no in-focus points on the image.  However I do agree the TC isn't helping the situation...

does not look focus point on subject

As posted before, make sure to have the combo (lens +TC) AF fine tuned. This combo is different from the lens itself.

Second, lower your expectations when it comes to a 2x TC and especially used with the lens fully open. The only TC that I've used or heard of that actually performs is the Nikon 1,4x.

Third, with the bird standing still use lower ISO and longer time, say 1/250, f8-11 and ISO 100-200

The 70-200 is a good sized lens.  It is longer and heavier when you add the TC2.0 to the mix.  A D850 is not a small camera either.  You could move to a slower speed as Bengan said above, but that might have more issues due to camera shake unless you are using a tripod or monopod.  Many people would have trouble hand holding that combo at 1/250.

[Bengan]

If the lens has VR I would not expect problems using it hand held at 1/250:

I use the Nikkor 200-500 and D810 combo hand held at that speed with no problems. Of course, a tripod is recommended.

[TBonz]

Agree.  There are those who can hand hold at slower speeds than others.  The old rule was to use the size of the lens (or the longest # on a zoom) as a reference so that with a 70-200, 1/200 would be the recommended slowest shutter speed.  But with the TC2.0 it would be 1/400.  It is simply a guideline.  I know people who can hand hold at significantly slower speeds and I know those who struggle to get tack sharp images with those #s.  As I've gotten older, I know I can't shoot at the slower speeds in some cases.
