All true- but remember they the games Tua missed in which they lost, was the soft spot of their schedule. (Titans, colts, Seahawks, jets)
Got to think they win 3 of those at least if he's healthy, which would have gotten them to 11 wins
I think with Tua healthy, they are a 11 win team pretty consistently. (8-5 in 2022 for games he started, 11-6 in 2023, and very good chance at least 11 wins if he played those games against inferior opponents)
However, they still are a flawed team and it will always be a struggle for them to win playoff games based on how they are built
