New England Patriots
If the Patriots go with three quarterbacks in 2018, this would be a fit. Lynch could learn from a Hall of Fame quarterback in Tom Brady while serving as the backup to no. 12 and Brian Hoyer. It would benefit Lynch tremendously.
The Patriots have a history in taking ahold of a former Broncos first-round quarterback: they brought Tim Tebow in when he was released by the New York Jets. It didn’t work out for either party, but it just proves that the Patriots could have an interest in Lynch, another guy who has not lived up to his draft position.
Behind Brady and Hoyer is rookie Danny Etling.
New York Giants
In the Big Apple, the Giants have a two-time Super Bowl Champion at quarterback in Eli Manning. Behind Manning is Davis Webb, rookie Kyle Lauletta, and Alex Tanney.
While the Giants will not keep four quarterbacks, there could be the option of putting Lauletta on the practice squad.
The Giants currently have three former Broncos wide receivers on the roster: Cody Latimer, Kalif Raymond, and Hunter Sharp. This would provide familiarity for Lynch in the event he ends up with the Giants.
