I think you're missing some very important parts. Things like short sprints 20s, 40s, 60s, and overspeed training.

a harness connected to a parachute or sled helps a lot too...If neither of those are available, just put on an old shirt and have a buddy grab on to your shirt and provide resistance while you sprint (better to do this on grass)...Also, try running in the pool. You may look goofy, but it works. I used to do these things for soccer, and they work wonders.

if youre going for speed id lower the reps of mondays workout so you can handle some push some big weight, especially on those squats.  5x3 would be better imo.

working on explosive phase
vertical: 35
weight: 206

Big 3: 300/440/515

Strength and growth come only through continuous effort and struggle.

Thanks ppls for all the help i'll try the lower reps heavier weight, and the shorter sprints/overspeed as well.
