Biggest question marks would be cornerback and OL due to a lack of guards and centers.
Jim McMahon and Steve Young @ QB
OL of John Hunter, Eli Herring, Elewonibi, Trevor Matich, Scott Young, Eric Bateman?
RB of Luke Staley, Jamaal Williams
TE Chad Lewis, Dennis Pitta, and may as well have 3 TEs out there and add Itula Mili/Doug Jolley
WR Cody Hoffman, Austin Collie, Todd Watkins, Glen Kozlowski, Mark Bellini
Defense:
DL Ziggy Ansah, Jason Buck, Brett Keisel, Hoke
LB Kyle Van Noy, Rob Morris, Bryan Kehl/Poppinga
DB Kyle Morrell, Brian Mitchell, Daniel Sorenson, Rice, Aaron Francisco/Tom Holmoe
