Good stuff on the squat PB though as others have said your knees appear to be buckling and i would guess 285 is very near your max. Read the following . Knee buckling is due to weak adductors.
Do Olympic Squats help you in your wrestling or why do you do them? It would be difficult to change (but not impossible) after you started out doing something and have done it all your lifting life. I saw you mention box squats and they are supposed to be done for speed work. I don't think Oly lifters do box squats.the form does change with hip drive, i dont feel the same squatting with it. i think i feel weaker because i have squatted with olympic squats for almost a year now so i am more used to that.
you thinhk i should stick with olympic squats? or vary like you said?
