Query: A wonderful lens

I sold my Nikon stuff for Canon, I was using the Sigma 70-200 f/2.8 which was very nice. When I moved to canon I was going to get the Sigma lens again (shooting soccer) I wasn't having any luck finding a used one reasonably priced. I researched the Canon 200mm f/2.8 and decided to try it. I couldn't be happier. The AF is faster and more accurate. It is very easily hand held(I usually put the Sigma on a monopod) I love this lens.
