Need Linebacker tips

I’m currently an upcoming junior in highschool and i want to be great at middle linebacker, is there any tips on what i should do?

My problems right now :
-can’t do my read step in the moment which messes me up
-need help on pass coverage as mine is iffy
-identifying offensive formations
-better angling for tackles

stats:
BW 180
Height 6’0
bench 195
squat 275 (stuck on this for awhile)
40 time i currently don’t know due to me not testing on it yet.

currently right now im focused on understanding offensive formations and dieting as im trying to get to 200 pounds. if you have any knowledge on
the above please share🙏
