I don’t think his lesser minutes was all injury. In games he was healthy, he would rarely get 30 or more minutes.
Next year, he was probably guaranteed more minutes and a bigger role.
Having the knee fixed in the offseason tells me it was something he was playing through the entire season in all likelihood.
Remember he missed a month or more last preseason with a bad knee sprain? His subsequent injuries were all lower body stuff too, but I think he was playing on this knee all season that was less than 100%. CH did same thing his last season here; said he was playing on “half my knee” or something iirc.
