I don't think speed wise Sagan is quite there vs. Cav, Greipel, Kittel, although with timing and tactics he could get wins. He is scarily improving year on year.
Cav seems to be a sprint tactics prodigy, and wins despite not pushing out as many watts as his competition. I'm not sure what kind of training Sagan does, but he's unlikely to be doing as much specific sprint training as his competitors.
