I have to agree with mike that body size and type are something that happens with regards to training. Training performance goals are always a better route. In mature, more advanced athletes a look at anthropometrics is something a coach can do. I'll look for more minute changes in my athletes at the HS level, like looking at areas surrounding the achilles tendon, the core, and shoulders as an indicator of leanness and fitness. That all changes when training is over a week old, because by then I have an idea of how what I want their early training performance goals to be and I'll know how they reached that musculature. This is something I believe that other sports don't do very well at, they emphasize the wrong things.
