stars are not "meaningless", there is ample statistical analysis (that has been posted on this board many times) that shows just the opposite.
again, it is very easy to point to the exception (Fisher), and yell "see!! see!!, i told you stars don't matter!!", but that is not indicative of the norm.
To your point, this is not a normal take for this staff. They obviously see something in this guy that the stars don't. Obviously if his 40 time is 4.6 rather than a 5.4 that is a HUGE difference in the star classification.
I trust the coaches on this one.
