Agree with
@TerryP about the dead legs! Nothing affects your overall game than having dead legs. Your jump shot suffers, you are a step slower to close out on a shooter, you have less explosion in your leap for a rebound.
I recall back in my HS days, my basketball coach was working the piss out of us the day before a big game. The end of season area tournament was starting the next week, so the explanation he gave for my question held no weight. We had scrimmaged for 30 minutes, drilled for another 45, and then were in the middle of conditioning when I asked āWhat good is all of this going to do us tomorrow night?ā Coaches response, āTo get you in to shape!ā In my usual smartass fashion I snapped back āWell, if we arenāt in shape now then we sure as Hell wonāt be in shape by tomorrow! My legs are dead as are everyone elseās!! We will get our ass run out of the gym!ā He told me to shut up and run! I ran, but I sure as Hell didnāt shut up! Another 20 minutes went by and it turned into an explosion in his office! In the end, we got our asses drug up and down the floor the next night and then lost in the semifinals of our area tournament the next week to conclude my HS basketball career! I was right!!
