Trade Builder

This one's for Wabbit. The league's most prolific trader — a true fantasy football day trader — used to evaluate every deal the old-fashioned way: fire up a spreadsheet, manually look up salaries and contract lengths for both sides, calculate escalation percentages by hand, and hope nobody fat-fingered a decimal point. If anyone was going to stress-test a trade tool into existence, it was going to be the owner who treats the trade wire like a full-time job.

Select any two teams, drag players and draft picks between them, and watch the salary cap impact update in real time. The tool automatically calculates multi-year cap projections with the league's 10% annual escalation, because nobody wants to discover three years from now that a deal they loved in February is eating their cap alive. By default, it suggests the two teams with the most cap room — on the theory that cap-rich teams make the most willing trade partners — but you can switch to any matchup in the league.

Mock drafts let you rehearse draft night before it happens. The Trade Builder does the same thing for trades — run as many scenarios as you want, see exactly whether the cap math works, and walk into the negotiation already knowing the answer. No more spreadsheets, no more guessing, no more "I think that works under the cap." Early reports suggest Wabbit's trade volume is up roughly 30% since launch, which is either a ringing endorsement or a warning sign depending on whether you're in his division.
