"It's totally different right now," he said. "My body feels a lot different. I'm excited to keep getting out there with my teammates and with Philip [Rivers]. We want to get that connection down. Last year, I was able to go out there and play, but I wasn't the Mike Williams I am used to being. I was limited in doing what I can do, and especially limited in what I do best, which is go up and get the ball. My back limited me from doing those types of things. Now my back is right, I'm healthy and feeling great. I'm ready to go out there and show everyone they've got a great player."
