BMI is flawed in the sense that it doesn't account for muscle mass. Anyone who is active and physically fit/athletic, is going to trend higher on the BMI scale and this doesn't mean they are unhealthy. BMI is a good ballpark indicator, but should really only be looked at it as a part of the entire package of data of ones physical well being.
6' at 136 vs 6' at 180 is a pretty realistic range of comparison for someone who is physically fit and active (i.e. has some muscle mass) vs some who is sedentary but practicing a reasonably healthy lifestyle (little muscle mass but has good dietary habits).
