Raonic looks very good to me. The serve will always help him out so it's the other parts of his game I check out. There's quite a few areas that needs work but all of them can be improved quite a bit. Physically he still looks a little awkward at times as many do at his age. This should pass pretty soon. Mentally he holds together pretty well and is so important in pressure situations. This is one area that has to be there when playing the best. He looks to be around a top ten player right now and could cause a few upsets at any time.
