I like the group.
Love
RB -- Reggie Davis
WR -- Keith Williams
OL -- Mike Cavanaugh
LB -- Trent Bray
DB -- Charlton Warren
All the support staff -- especially Ryan Gunderson and Andy Vaughn.
HC -- Mike Riley. Maybe most importantly.
Pressure's on
OC -- Danny Langsdorf
Playcalling, recruiting. Good resume, but much will be asked of him. Beck was solid and does leave some shoes to fill, especially in recruiting.
Question marks
DC -- Mark Banker
Biggest question marks by far. Let's see how he does with the defense, and with recruiting. And, hugely, if he doesn't cut it, would Riley be willing to make a change?
DL -- Hank Hughes
Banker believes in him and has DC experience. Recruiting?
ST -- Read
Has to show value in all phases of special teams play, not just kickers/punters (which I think is what he's known for). Is out on the trail recruiting but will he be an asset there? Still, you figure his job security is probably going to be very good.
