1. Which quarterback icon has been toughest to replace?
Chad Pennington, Chad Henne, Joey Harrington and Jay Fielder. It hasn't been pretty at QB for the Dolphins since Dan Marino left. But is it worse than than the 49ers (Tim Rattay, Shaun Hill, Alex Smith, among others) or the Broncos (Brian Griese, Jake Plummer, Kyle Orton and Jay Cutler) without legends? NFL QB ranker.
