Being good at clutches is a different thing brother. In a clutch you don't have to account for all the different possibilities that enemy could execute be it a rush, nade set exec or contact play. To have impact with the AWP you actually have to be able to smartly out position and anticipate your opponents.
Ex. device is a great AWP but he never clutches with awp in hand. He preferably picks up a rifle every time. Hope you understand.
