You're onto something that they're all tackles, but you have it wrong. The reason they're all tackles is because that is where every team puts their best linemen, not because they are facing weaker opponents. Tackles simply have a lot more TPE than guards or centers.

I was also thinking that DEs in the league generally have more TPE than DTs, though, so it somewhat evens out.
