Why doesn't NY trade Nova?

This dude is terrible! He always gives up 3-4 ER's or more per game! That's horrendous even for a young pitcher. And don't give me that nonsense that he's young! Seattle's young pitcher yesterday did real well and so do other young pitchers, way better than this stupid bum! Why doesn't he get traded already, he lowers our chances of winning every game he's on the mound. He needs to get traded ASAP if anyone even wants this piece of garbage! Who else agrees with me on this? This guy needs to go! Our other pitchers are doing ok but he hurts our chances every time he throws the ball, always having bad command and control and giving a wealth of runs, even to the horrible Mariners!
