Separation metrics might be one of the dumbest stats out there. Tons of great WR's have terrible separation metrics because they are X WR's who catch passes in tight coverage. Slot WR's and TE's routinely have great separation metrics because they have a two way run with routes and run tons of crossing routes and go in motion. I also had a nice chuckle reading about 2 pages back about how there was no way the offense could continue on like it did last year and here we are 4 weeks in and probably doing even a little better.
