Best x factor for WR?

The ability tier list on here says it's YAC.  It's decent but my understanding is a major component of it's ranking is that the YAC one at least actually works. So you may have some luck with that.  

It's ranked lower in the ability tier list but Max Security has is truthers. They swear that it helps them catch balls where they're double and even triple covered. Plus it supposedly helps with beating press. At least according to those who have success with it.

At least on xbox series x/s and ps5 I haven' had much success with double me. In my personal experience, receivers without it play just as well as receivers with it active.
