Trade "high", wait a little longer or keep ros?

Hey everyone, so far pretty much everyone on my team has been underperforming based on what they did last year but they all had pretty good games this week so I was wondering if I should try and sell them now, wait one more week or keep them for the rest of the season
James Connor, Sony Michel, Joe Mixon and Adam Thielen
Thanks in advance footclan

Any and all advice would be appreciated, I have no clue what I should do with these guys lol
