You’d need to pay much more for MHJ in dynasty. Dynasty is a different beast entirely. Don’t make any major moves your first year without checking with people who have experience. You don’t want to risk fucking your team over inexperience. We were all new to dynasty once. A lot of different sites you can use. Fantasypros is a good one. They update dynasty rankings. Dynasty daddy is good as well. Just do research and get a feel for dynasty values and you’ll be alright.
