Devery Henderson was a good deep threat for Drew Brees.
The Patriots are very thin at wide receiver and need to pick up one through free agency. Tom Brady needs a new deep threat and there are many speedy free-agent receivers.
First off is Darrius Heyward-Bey, who has tremendous speed and was a top-10 pick in 2009. The former Maryland Terrapin was productive in his past two seasons and caught 11 touchdowns over four seasons with the Oakland Raiders.
Heyward-Bey would flourish by having Brady at quarterback.
Free agent Early Doucet was limited last season and not much of a factor in the Arizona Cardinals' offense. It's not all his fault, though, as the Cardinals did not have a reliable quarterback and even Larry Fitzgerald was negatively affected in 2012.
Two season ago, however, the 6'0" Doucet caught over 50 passes for five touchdowns. He could be solid in a Patriots uniform this season.
Former Saints receiver Devery Henderson was a big weapon for Drew Brees over nine seasons, grabbing 20 touchdown passes. While he may be on the downside of his career, Henderson could still be a solid deep threat for Brady.
Another option may be Steve Breaston who spent the past two seasons with the Chiefs. Like Doucet, Breaston had a tough 2012 season. He has been solid over his career, however, having at least 700 receiving yards in four of his six seasons in the league.
For the Pats to use Danny Amendola and the tight ends effectively, they will need somebody to be a deep threat to stretch the defense.
