Hard to say for sure, but I'd guess the odds of Sloter making it through wavers so we can put him on our practice squad are around 80%.  It's easy to forget that lots of teams have rookie (or UDFA) 3rd QBs that play in the preseason and look good against 3rd/4th stringers.  There will probably be 20 Sloter equivalents cut on Saturday and resigned to practice squads.
