Physics.OverlapSphere not giving proper coordinates

So Im trying to use Physics.OverlapSphere to get a set of objects around the object with the attached script. when testing its showing their locations to be exactly the same, I cant figure out why, please help.

     curVec = nextRoot.transform.position - curRoot.transform.position;
     Debug.Log(nextRoot.transform.position);
     Debug.Log(curRoot.transform.position);
