But the owners don't want them to block legally, or do they want to change the rules (which is what should be done), as Owners want their QB protected and to score more points.

I think it was 9 time All-Pro Cowboys OG Zach Martin who famously only has 10 holding calls in 11 years of playing in the NFL who admitted...

He was always ABSOLUTELY SHOCKED when he got called for holding... because he wondered what set it off, as he was only called for holding 10 times, but he admitted he illegally held players about 50% of ALL HIS SNAPS...

So he wasn't shocked he was holding, just shocked that the refs called it...
