I'm amazed that a manager as slick as you is thinking about tanking games for the sake of a better draft position! Seriously, winning games brings in more revenue since you can sell more tickets at homes games and/or raise ticket prices. More money means you can buy a better player from the TL to keep up your winning ways. Oh, and winning is usually a pretty important objective in this game. You don't need prospects at this point, and the draft can be very unpredictable anyway. I don't think there's much of a question here. Just win.
Don't ask what sort of Chunks they are, you probably don't want to know. Blowing Chunks since Season 4!
