Trade Lab is a free fantasy football trade analyzer. Import your Sleeper or ESPN league and it shows how any trade changes each team's projected points, playoff odds and title chances, instead of just adding up trade values. It also finds trades the other manager is likely to accept, tells you whether to buy or sell before the deadline, settles start/sit calls, and grades the trades your league has already made. No account is needed to try the Trade Analyzer or Who do I start?.
