I know these two abilities are supposed to work the same in pass protection but has anyone tested this to see if they truly do work the same on Offensive Tackles?

I have CH2 Kolton Miller at LT with Edge Protector and he has outperformed any other LT I’ve used. He has played 38 H2H games and only allowed 1 sack in a total of 501 snaps.

I can’t figure out why he’s played so well for me. I have Secure Protector on my RT and I feel like I’m always getting pressure/sacks over there.
