I agree with you... I just think it is being overemphasized re: this year's team because nobody has ever had four starters so old. For what team is "HEALTHY" not the keyword? Curry went down last year and the season was over for Golden State. Same would have been true for the Thunder, Nuggets, Pacers, Wolves and any other team losing its best player. How many teams do we think can win if their second best player gets hurt?
I gave that example of the considerably younger 2022 Warriors team to demonstrate just how important "HEALTHY" is for any team that isn't historically great like that 2018 Warriors team that could have won without KD if Klay had not gotten hurt also (or vice-versa). It is extremely extremely rare that "HEALTHY" is not key to any team's title hopes so we don't have to belabor the point with the Warriors just because they signed Al Horford, which is really the only reason it is so discussed heading into this season, along with how last season ended.
