These one-day contracts are becoming fairly common so that players may retire with the team they spent the majority of their career with (ie: Jerry rice). When Jason is ready to retire, I don't have a problem with him getting a one-day deal to retire on. Then again if he retires as a Texan or whatever, I don't have much of a problem with that either.
The Hall of Fame is a different story. If he is ever inducted the he absolutely has to go in as a Dolphin. Let us not forget the great Red Sox hitter, Wade Boggs, who spent all of two years in Tampa Bay.
