If so, it makes me somewhat nervous. In any case, whoever is named will only mean that he is named to open at Miami.
Naming the starter at Miami is not that big of a deal in the grand scheme of things. He could play for one series, one quarter, etc. It's happened many times that the starting QB on a team ends up being replaced after a short while. If they are so close now, whoever is named could very well be replaced by the other until it is obvious that one is better than the other.
