The safety room is going to get better with coaching and experience because its so young. But you are trying to replace JJ3, so does the position get better? No.
I think WR3 could be better with Jefferson getting a year under his belt. He's a more physically and nuanced WR than Reynolds could ever be, so experience and coaching should improve that spot.
TE 2 - I think Hopkins has a real shot to be be better than Everett.
