I know it's hard to find replacements this late in the season, but I'm gonna try. Here are two teams available in my dynasty league. Mostly look to build for the future really. Trading is still open until 8/23 so if anyone wants to jump in, go for it.
I'll be honest... both teams are not in contention, but they still have some pretty good pieces to work with for next season.
