I look at it this way...
If the law of averages is actually a thing then eventually we're going to have one heck of a run as everyone gets back to their norms lol.
But I don't believe in the simplistic idea that the problem is just that everyone is missing shots. There is a reason why they are missing those shots, this team just isn't gelled and people aren't comfortable out on the floor, they are probably thinking too hard about where they should be and what their role is, whether it's ok for them to take a shot or not etc.
And absolutely that could be because more guys are in the mix now. If say, Jaylen Brown had more confidence on his place on this team I'm willing to bet more shots would start falling for him. Most of our guys just don't know what their place is on this team is right now.
