I don't think WRs should use super elusive unless
1. the CB covering them is extremely good (as in maybe he'll let up 1 pass to you out of 4-5 good)
2. the CB covering them is running on close coverage
3. the WR uses moves like juke or head fake to get open
4. the WR uses creative route running
5. the WR is not too interested in YAC, ie: they are more of a "possession build"
To me, it's not as much about how much of what stat you have; everyone is capable of running well on super elusive (yes, everyone will make stupid moves every now and then with it too) but it's not beneficial to you unless you need to use it to create space before the catch
that's just my experience with it
for the most part it's for elusive returners
