Yes.
A good way to think about replacement level would be ... oh I don't know .. Bobby Dalbec. He's not really good enough to be a real big leaguer, but he can play in a pinch. I believe based both fangraphs and bbref reached an agreement on how to interpret replacement level that way. Now, I am not sure of the details - but a good rule of thumby way to look at it is that a team made up entirely of replacement players would be expected to be a real major league team, but the worst one in the league. Let's say 50 wins.
So the Orioles ended up with (as a team) 16 combined WAR from pitching and 28 WAR from the position hitting/defense. That 44 WAR if you add to 50 gets you 94 wins, and their pythagorean record was 94-68
Atlanta 39.2 WAR from hitting/defense, 16.2 WAR from pitching = 55.4 combined WAR ... 105 wins ... their run differential speaks to 101 pythagorean wins
Red Sox 17.2 pitching WAR, 19.1 batting/def WAR ... 86 wins ... pythagorean 81 wins.
Oakland 0.0 pitching WAR, 11.2 batting WAR ... 61 wins ... 49 pythagorean wins
So this is not exact, but you get the rough idea. So, looking at bbref. The median team in 2023 was about 18 WAR from batting/fielding. That ends up to about 2 WAR per player/season. If you back out 10% for what seems to me to be a fair number of rest days or whatever (so 146 starts) that gets you to about 1.8 WAR for a full season starter as an average position player/DH.
0.5 WAR (whatever flavor) sucks - assuming we are talking about a large number of plate appearances. Basically it means that means you are only slightly better than any ole Rick Lancelotti/Crash Davis type of up-and-down guy.
