I don’t know your situation, but here no one is doing ‘sprint training’ (or speed training) in real meaning of the word - high intensity effort (95%+) and long rests (at least 1min/10meters between resp and 2-3x longer between sets).
So, I think it is under-rated here.
Do I agree it is hard to develop it in so much dense comp schedule? Yes, I do. Is it important to be developed. Yes, it is (from physical prep standpoint). Do you need to do sprint training to develop speed ONLY? No, you don’t. There are tons of more specific tasks that develop it, along with some technical/tactical element.
