BSH on offensive linemen

So I’m confused about this BSH thing for offensive linemen. It came from a content creator? Who? Can anyone point me to where I can find this info?

Also I’ve been looking at the stats on offensive linemen I’m debating doing some testing because this isn’t making much sense to me.

The best linemen in the game according to this logic are if I’m interrupting things correctly

1- 92 Tristan Wirfs with 11 BSH

2- 90 Coleman Shelton with 10 BSH

3- 89 Country Strong with 12 89 Armstead with 11 89 Zeitler with 10

Then the best overall linemen in the game

93 Larry Allen has 17 BSH

95 Woody has 19 BSH

95 Yanda has 25 BSH

95 Mack has 26 BSH

95 Dierdorf has 45 BSH

So I assume testing Wirfs vs Dierdorf would be the easiest way to see if there is anything to this. Wirfs should occasionally get beat out the gate when Dierdorf does not but should on average hold his block longer. Correct?

Might be easier to test Zeitler and Yanda. Easier numbers to work with and same position. Smarter not harder.

Secondary implication of BSH being relevant to offensive linemen is impact block being relevant to defensive players. Old news?

I don't think blockshed does anything for Oline. They had to put a number i guess so it wasn't 0
