ESPN 12 team Roto Dynasty League with 5-man minor league rosters. Keep 25 major leaguers from your active roster each year. Minor League draft each offseason in the spring. (No salary cap or anything like that.)
There are potentially 2 teams available. Both rosters are in surprisingly good shape (several young stars still in their prime and budding stars already on them) and are picking high in the upcoming minor league draft so you'll be in a prime spot to add more high upside talent immediately.
This is a long standing league with guys that are active and genuinely care. Send me a message with your email address and tell me a little bit about your experience in keeper leagues & dynasty leagues. (Just want to make sure you're committed and enjoy the long-term leagues as much as we do. This isn't a test, we just want to know you have a track record of sticking around and staying active.) Feel free to ask me any questions in the message too; I'll let you know about the 2 teams available.
I'm interested. My email is firstname.lastname@example.org I am the commissioner of a keeper league that is going on its 4th season, I haven't done a dynasty league yet, but I've been very interested in joining one.
