Spot on. Lot of players use sens that is good for rifles, but when awping they cant make fast/big flicks and use movement trying to compensate low sens or simply its the thing of reflex when you try to avoid getting shot and you try flick at the same time. Most likely lack of mechanical training. Lot of pros dont even play Cs besides camps and officials. Thing is training is constantly needed thats why Simple is so good. He always train in aim maps, mm, fpl and stuff.
