Backup Quarterback, not being Koy

I don't understand the many Philly writers who insist that the Eagles have to upgrade the backup QB position - with the implicit understanding that the Eagles jettison Koy Detmer. And I would not be so quick to dismiss Akers' preference for Detmer as his holder as several writers have done.

First off, what kind of upgrade does anybody think we can get at QB? Here's a quick list of current backups off the top of my head: Sorgi, Davey, Tuiasosoppo, McCown, Romo, Ramsay, Rodgers, Dorsey.

Are any of those guys a significant upgrade from McMahon and Detmer?

But my bigger question is why everyone wants to cut Detmer, elevate McMahon to #2 and bring in a younger, better QB as #3.

Why?

Why doesn't the current arrangement work? Detmer holds for Akers and is the QB "on call" so to speak during the game in case McNabb gets hurt and can't play during a game. As we've repeatedly seen, Detmer can play and has the ability to move the offense.

should a McNabb injury require him to miss actual games from start to finish then McMahon gets the start and Detmer remains at #2 on the depth chart - still holding for Akers and ready to play in an emergency should McMahon get hurt. What is the problem?

The Eagles have a pro-bowl kicker. Given the Eagles' long history of futility at that position, it would make a lot of sense to keep that player happy and maximizing his potential to score. If that means keeping Detmer as the holder so be it.
