2021 Fantasy Baseball Platform Central -- Yahoo!, CBS, ESPN, Fantrax, etc.. in Fantasy Baseball Talk Posted March 3 8 minutes ago, The Big Bat Theory said: Leagues all have the same mechanics. What happened once with me in a dynasty league was some guy I wanted wouldn't clear waivers until the day after the season ended. I put in a claim the night before for the heck of it. In the spring I had the guy on my roster though he didn't show after teams were locked for the year. Just when they went down for the database updates and came back up and there he was on my roster, haha. But another more common explanation is in private h2h leagues you can select when playoffs start and end and some leagues choose to finish their championship finals the next to last week of the season so half their star payers won't be sitting on a bench like MLB teams tend to do with their regulars in real life then "resting" them for the playoffs etc. In that case the league remains open until the last day of the Yahoo season period like every other Yahoo league. Even if you can't play games that week. So that last week you still can make all the drops and adds you want up to your league's limit per week. Which is a good thing. Gives you one more week to look over your roster and see who you will want to keep or not and if anyone is out there in the free agent pool you prefer. Even make a quick trade. Wonderful week getting you set up for spring. Must have been something like this. Usually people don't care after the season but I guess in a keeper people should!
