Interesting information, thanks. Recently started looking at these defensive props - see what you mean with WAS assists, looks like SEA, NE, BAL, BUF, WAS top 5? Do you ever split it in more detail such as conference vs non conference games?
I'm not sure the opponent matters. The way I understand it there is a scorekeeper or stats crew at each stadium, and they have different tendencies regarding how they assign tackles. Some are more predisposed to hand out a single solo tackle to the player primarily responsible for a tackle with no assist given out to anyone else who may have helped. Some are more predisposed to hand out 2 assists on a play rather than trying to pick out the player most responsible for making the tackle. And then some hand out a solo to the person who made the primary tackle and an assist to somebody else who contributed. Both of the latter two wind up awarding 2 "tackles" on a single play when they do this, which can inflate the overall numbers so you wind up with plenty more tackles awarded than actual tackle opportunities in a game.
I haven't spent much time breaking down how much this helps home vs away team as I think that difference will be rather small in comparison to the other patterns that emerge when you break things up by stadium or stat crew.
My top-5 last year for combined tackles/tackle opportunities were BUF, NYG, SEA, BAL, and WAS.
My bottom-5 last year were PHI, KC, JAX, MIA, STL
top-5 crews gave out about 52 assists per game on average (averaged about 1.28 tackles per opportunity)
bottom-5 crews gave out about 10 assists per game on average (averaged about .97 tackles per opportunity)
So, when you play a prop that treats solos and assists equally, that stadium impact can play a huge role and provide a big edge. I assume it should get factored into the lines already, but they don't always appear to account for it enough.
