Yea my arms are short so I have to be right up on someone if I want to bother their shot. Most of the time I'll start off close right up on someone for that very reason... it bothers a lot of people and they won't want to do anything. For someone who is good though... that's what they are hoping for lol. They will most likely blow right by me because I don't have the quickness to stay with someone from that close... but even still, I figure I might as well make them make a play rather than just dance around and get an open jump shot cus they shook me
Quick lateral movement is difficult to attain... change of direction takes such incredible force it's ridiculous.
