I think you misunderstand how the phenomenon arises.
It is the typical situation whenever there is random variation.
Let's look at the number of heads in 10 tosses of a fair coin. I do the set of 10 tosses and get 7 heads. Next I do another set of 10 tosses and get 4 heads, and so on. Let's imagine we like heads - 10 heads is a great performance for us and 0 heads is a terrible one, while 5 heads is average.
This will have exactly the property you mention -- a great performance will (nearly always) be followed by a less perfect one; similarly a terrible performance will nearly always be followed by a less terrible one.
But it's just a coin. It has no memory, it can't learn, it can't feel good or bad and it has no 'streaks' of performance (nor does it possess any 'anti-streakiness'). It simply knows nothing of its previous performance. There's no information in the previous good performance that will help us predict the number of heads next time.
It's just randomness.
If I get 10 heads, the chance that I get fewer than 10 heads is 1-P(10 heads) = 1023/1024 (so there's definitely a high chance I will perform less well the next time). But that was also the chance I'd get fewer than 10 heads if I previously got 5 heads -- nothing changed. The "10 heads" is of no value in prediction of the following outcome.
Now it may be that there's something more than this simple form of 'regression to the mean' going on in your favourite sport but you'd need to investigate to find out -- there's nothing inherent in the notion that good performances are followed by less good ones that suggest there's anything valuable in seeing it, it's a natural consequence of typical sorts of variation from one performance to the next and may be nothing more than the vicissitudes of chance.
Even in situations where good performances happen in streaks (above average performance tends to follow an above average performance), you would nevertheless still see that a great performance would nearly always be followed by a less outstanding one; taller than average fathers have taller than average sons, but on average the sons of the tall fathers are more often shorter than their fathers. This is regression to the mean.
