How does Sliders really work...?

[Mike Mussina #35]

Hey Guys,

i tried to get good sliders, but i have a problem by understanding the use of sliders.
i.e.: hands on perimeter, shot alter ability, hands in post, close out effectiveness and help side defensive effectiveness...

what means it if i take them high rated near about 100 and what means it if i put them down to or near 0?

Thanks for help...
