Ok...let me try to explain it.....
Football, yeah, Football might work...
Linebackers tend to be big, strong, powerful guys with relatively high BF%
Think.....Zack Thomas
Receivers tend to be big, strong, powerful guys with low BF%
Think......Terrel Owens.
Now, if we could stick a air hose into these guys and "blow them up", like creatine would do, both would get bigger.
But...
With no change in BF%
The linebacker would look big, swole and fat.
Think.....Warren Sapp.
The receivers would look big, ripped, and great.
Think.....David Boston
For further evidence...take a look at a recent picture of David Boston...think me may use creatine (along with a ton of other stuff)?

Looking "thick" or "bloated" may not be a concern of many males but for females in general, that look is not something desirable.
I hope this clears things up.
