"Packers Congratulate Eight Punt, Pass & Kick Winners From Sunday
posted 11/30/2008
WAIT IS ON TO SEE WHO WILL COMPETE AT NATIONAL LEVEL
The Green Bay Packers hosted the team championship of the annual NFL Punt, Pass & Kick competition Sunday prior to the Packers-Panthers game."
When the PP&K contestants out-kicked Frost prior to the game Thompson finally decided he couldn't wait until the end of the year to make a change.
Note the "WAIT IS ON TO SEE WHO WILL COMPETE AT NATIONAL LEVEL".
That's why they haven't announced a new punter yet--they're in negotiation with one of the contestants. π
