Ah, good. I literally laughed out loud at the comparison to crossfit.
In my short experience, in season or during a 'explosive' block of work my squat/dl usually go down a little as well. I contribute this too a few things.
1. Less volume and therefore less time practicing the movement.
2. Skill work and conditioning do nothing for strength, in fact they usually have a detrimental effect.
3. The explosive stuff (DJs, bounds, etc) programs your neural and musculature circuits differently. Your body gravitates from being comfortable in a squat motion to being comfortable and therefore more efficient in another (jumping, running, whatever)
With that said I have also noticed this weird conundrum with myself. I train a strength block and add say 20-30lbs to my squat and its now 300lbs (vert doesnt go up much or at all, we'll say it stays at 30" for comparison sake). I take up a explosive block and my vert shoots up a few inches, and squat strength goes down. Now, funny part, I go to another strength block...I can't do 300lbs so I go down to 275. Work my way up to 320 or whatever and my vert stays where it was after the explosion block and doesn't decrease while I cut back on reactive stuff. So it keeps going up faster than my weights are. This has happened twice now. Just my experience but still a thought worth considering.
Basically, you're playing alot (see point 2) AND you're cutting. So don't worry about losing some squat strength as long as your displaying a more explosive you on the court?
