Do I need to upgrade my team?

Currently sitting at 3-4 in a 12 team league. Full PPR Most people are sitting at 4-3 so it’s still close to not go crazy but should I look at trying to make some changes? DJ Moore is hit or miss but has looked better last few games and have cmc coming back next week which will hopefully be a big help if he is fully healthy. Any suggestions?

I mean your team is pretty solid for a 12-team league. Considering it’s close, I would just try to hold on until CMC is back
