The only thing I dislike about yoga as a concept, or any "movement" system, is that extreme feats of flexibility and strength are often used as a measuring stick for beginners. That can be very counter productive, and most of the time modifications to movements are key to insure the best results for everyone. Another thing I do not care for is the mysticism of it all. There's nothing mystical or magical about it.
Yoga is, in its essence, various forms of movement and mobility systems mixed in with breathing, control and mental focus. That is excellent for anyone, including athletes. I'd pick a short and simple yoga routine and do it as a warmup a few times a week to begin with. Play around with a few of the movements and see which modifications feels best for you. Later you can expand on it if you want to.
