Why McCoy fits: He previously played under current Patriots assistant Brian Daboll in Cleveland (2010), and thus has a background in a Patriots-type offense. He would add an experienced third option (21 career starts) behind the two signal-callers entrenched in the top spots on the depth chart.
Why Quinn fits: Similar to McCoy, he has experience in a Patriots-type system from having been on a Brian Daboll-coordinated unit in Cleveland (2009) and Kansas City (2012), and a Josh McDaniels-coached team in Denver (2010). If the Patriots are considering the addition of a third quarterback, it makes sense to look toward a player coaches are familiar with.
Why Smith fits: More of a developmental option, Smith (1 career start) spent the last four years with the Titans, who selected him in the sixth round of the 2010 draft. At 6-foot-5 and 226 pounds, he has a solid physical makeup and was looked at closely in the pre-draft process by the Patriots.
Market conditions: A top backup quarterback is commanding about $4 million per season, as reflected by the agreement between the Jacksonville Jaguars and Chad Henne. That is also around the range that Matt Cassel landed in his two-year deal with the Vikings. The Patriots would be looking at more of a cheaper, No. 3 alternative.
Questions to answer at the position: Will Brady show any signs of decline? Might there be any type of trade market for Mallett, who enters the final year of his contract? Will the Patriots draft a prospect, similar to what they did with Mallett in 2011?
