Achilles tears have always been thought of as career altering, but KD tore his achilles in the playoffs in the exact same way (in his mid 30s), missed a year and came back and might have even gotten more efficient. I think Tatum, Halli and Dame (we'll see I guess based on age, maybe he's the outlier) will come back fine. The bigger problem is that they're all max guys and their teams have to go a year without them and will all look different by the time they're back. I think the pacers are destined to lose Turner (he was awful all series so not sure if that matters) and nesmith before halliburton comes back. Rosters change so quickly in the nba that one burnt year can really kill you.
