You already have a 7DII, one of the 2 best sports and action cameras Canon currently offers, the other being the 1DxII. If you are unsatisfied with your results then you probably need to look at your technique. Buying another camera, even a 5DIII, which has lessor capabilities for sports and action, is not going to solve your problem. If you need a 2.8 for lighting conditions then the Sigma, even though I am not familiar with it, sounds like a good candidate. Sigma makes good lenses. If an f/4-5.6 lens will serve your purposes then I suggest you look at the Canon EF 100-400 L II. A superb lens for a lot less money then the $3500 you mentioned. Plus, you can zoom in and out. A handy feature. It's stabilization is top-notch and it's auto-focus is almost instantaneous.

Except for shooting indoors and / or low-light, the Canon EF 100-400 L II is your best bet for performance and range. Otherwise, you're looking for 2.8 lenses of the various brands that are more expensive and larger, if for no other reason, because of the size of the front element to give you a f/2.8 aperture.
