So learn to move your feet.
Thanks for the great tip displaying intellect of such high caliber, even if it comes across as a bit snippy.
However, I already know how to move my feet, but the point is that moving the feet, rather than just the gun, takes MUCH longer. One may not have time if Bubba and his friends have positioned themselves advantagiously. One can pivot to extreme right or left FAR more quickly than having to reposition the feet (and whole body along with them).
AND, if you have time, then position yourself the way you want.
