After a sobering Week 10 in the NFL in which four starting quarterbacks went down for the count with injuries — beginning with the Eagles’ Michael Vick and ending with the Steelers’ Ben Roethlisberger — an in-depth examination of the NFL’s backup QB landscape has never seemed more relevant.

Taking into account the league’s latest bullpen duty — which included a Sunday-night start for Byron Leftwich in place of the injured Roethlisberger, Monday-night starts for Bears QB Jason Campbell and 49ers QB Colin Kaepernick in place of concussed QBs Jay Cutler and Alex Smith, the starting debut of Eagles rookie Nick Foles in place of the concussed Vick, Cardinals third-stringer Ryan Lindley replacing an ineffective John Skelton and Chad Henne doing yeoman's work in place of an injured Blaine Gabbert in the Jaguars' near-upset of the Texans  — Pro Football Weekly has taken on the challenging task of ranking each team’s backup QB — from best to worst.

The way we ended up hearing it, after consulting with a handful of trusted NFL talent evaluators willing to lend their assistance — and weighing the delicate balance that comes into play measuring both seasoned experience in some cases against considerable starting upside in other cases — the relief pitcher providing the most capable repertoire for success with the 2012 season’s three-quarters pole fast approaching resides in Miami.

The more we researched the subject, the more convinced we became that Dolphins backup QB Matt Moore, currently No. 2 on the Miami depth chart behind rookie Ryan Tannehill, is worthy of being considered the NFL’s No. 1 backup QB.
