You’re really kinda overthinking things.
If you’re currently in-season, you do not need much (if any) cardio training other than going balls out during the game and working hard at practice.

This is usually a combination of the recovery issue again, or general calorie-burning that some people don’t take into account.
Again, if you’re in-season, your primary focus is not to improve your squats each week. Your primary focus is to win that week’s game.
It might, or it might not. Without seeing your entire training plan (days, exercises, sets, reps, cardio plan), there’s no way to specifically say “this” is definitely going to interfere with “that.”
But in general, “working the heart” won’t be the reason for decreased strength.
Dude, if your goal is to add size or strength, there’s a chance that poorly-planned cardio can interfere. However, if you have to (or want to) do cardio while training for size or strength, adjust the intensity and frequency, and make sure you’re eating appropriately around training.
