One thing to know: How will Broncos keep Manning upright?

After losing center J.D. Walton to an ankle injury and replacement Dan Koppen will be out with a torn ACL, Mike Florio asks the biggest question facing the Broncos right now: Who will protect Peyton Manning?

It will take money, time and possibly draft picks to recoup their losses on the offensive line, but Florio says not to expect a return of former center Jeff Saturday. Saturday, who is enjoying his new gig at ESPN, has slimmed down to 230 pounds, making it hard to envision him stepping back into his former role.
