I know what you're thinking—isn't it too soon to be considering trades? I just drafted my team!
It's never too soon. Maybe somebody in your league drafted purely for value and is looking to make deals to better balance their roster. Maybe somebody auto-drafted and got completely shafted at one or two positions. Maybe somebody absolutely loves a particular player but just missed out on drafted him and wants to swing a deal.
Whatever the case may be, you should always be open to opportunities to make your team better. And if trades present themselves, you want to make sure you're getting the best deal.
