I still remember the time I was watching Rasheed Wallace in warmups spotting up and having an equipment guy feed him passes while another equipment guy rushed at him to block the shot. He must have made 24/25 with the guy right in his face and he has never been an elite shooter or anything. Standing in one spot and making shot after shot really isn't that hard.
I guarded Sheed several times in 5 on 5s and word to the Gospel he had a spin-move 3 pointer that was automatic in college. His tall ass would do a cross into a spin into a fadeaway 3 and it was all net every fukking time. It was unguardable. His skill set - which he rarely took full advantage of - was plain fukking amazing.
