Basic answer is that the 2x III can offer excellent increased FL on certain AF-S lenses ( mostly f/2 to f/2.8 ). It also works nicely on certain f/4 lenses. I use it on the 300 f/4 and 200-400 f/4, but the focus may be less certain in poor light. It also saves the weight of bigger telephoto lenses.

What camera body are you using ? FX or DX ? That makes a difference for ( say ) rugby field range.

In your rugby-shooting plans, why not consider buying a previously-loved 300 f/4 AF-S ? You could always sell it in a couple of years at near your purchase price, if your needs change.

It is a superb value for big-field sports like rugby on DX bodies, where one needs a range betw 300 and 400mm. The 300 f/4 is optimised for its max range of 300mm. It will focus more quickly, compared with a 2x TC-equipped lens and is sharp wide open at f/4. Using any TC demands that you stop down a bit for improved IQ, as others have suggested. Using the straight 300 f/4 means that you can use it wide open for sharp pics.

If you found that you really wanted to be a bit closer, you could consider adding the 1.4TC which is a perfect match for the 300 f/4. It is the best Nikon TC, having almost no effect on focus speed, 300 f/4 and takes the aperture to f/5.6, still bearable, though better stopped to f/6.3 

Also consider a monopod for improved results in fast-moving sports shots from the sidelines, esp when you get into the 300mm and above world.

Good Luck,

Keith
