My initial reaction was disappointment, but upon reflection, it does minimize the risk of serious disruption while the Dolphins are still in play for a Wild Card slot. On the other hand, it would be nice to get some closure and just move on.
Wells is still interviewing players in Miami all this week. I bet with Miami in the playoff hunt the NFL doesn't want to release anything till the Fins season is officially over. Not to create a circus around the team with 3 games to play who has a shot at the playoffs.
