I shoot kids sports, primarily.
Currently have:
Canon 70-200mm f/2.8L IS ver 1
Canon 24-105mm f/4 IS USM ver 1
Canon 50mm f/1.8
Canon 1.4x Extender II
I had purchased a Tokina 11-16 f/2.8 Dx II, and only used it for two vacations over a few month span. Before I really understood how to utilize it, I sold it. Really wishing I would have kept it now that I'm itching to get more creative.
Thanks in advance for the advice.

Your camera bag almost identically mirrored mine, before I completely revamped it. Given that you're focused on shooting kid's sports; and you have a $1,000 budget. My thoughts would be the Sigma 150-600 Contemporary lens.
I'm not sure what type of children related sports you're referring to, but the Sigma 150-600 was paired well with my 7D MkII for outdoor youth football, baseball and soccer.
I sold both, the 7D MkII and Sigma 150-600, to generate some cash to purchase the 1Dx MkII and Canon 100-400L MkII. And, I can honestly say that I miss both. I may repurchase the 7D mkII, because of the crop factor; and may purchase the Sigma 150-600 Sport.
