Let me say up front, I made a mistake. I meant to reject a trade offer and somehow managed to click 'Accept'. If there were not a feature for undoing my mistake, I would have to live with it and chalk it up as a lesson learned the hard way. But there is such a feature!
League Admin's have the ability to 'void' trades. Probably originally coded to undo egregious unfair trades stemming from collusion, deceit or naive new owners, but also useful for reversing mistakes like mine - except that it fully work. Voiding the trade
https://ncaa.myfootballnow.com/trade/439 has left the players on both sides livid with BOTH owners, and our dead cap impacted from the bonus portions of the players contracts that triggered upon the first trade. The current year dead cap hit isn't a big deal, because whether I trade them again, cut them or keep, the net impact to my CAP is the same. But the inability to re-sign livid players I never meant to trade, and the dead cap next year (22mil) not being reversed is an unfortunate oversight of the 'void' feature. Effectively all void appears to do, is make the same trade again in reverse, not actually 'void'.
Not sure if this qualifies as a bug or enhancement, but league admins and owners beware!!
