The Jets will spend much of this offseason beefing up the offensive side of their roster. And they took a step toward that goal by signing tight end Jeff Cumberland, the team announced Saturday morning.

Cumberland's deal is for three years, according to a league source.

After years of being a backup to ex-teammate Dustin Keller, Cumberland had his best season in 2013, catching 26 passes for 398 receiving yards and four touchdowns. He began last season as the No. 2 to free-agent signee Kellen Winslow. But it's clear the Jets are expecting Cumberland, 26, to make a dramatic leap starting in Year 5.

Cumberland was set to become a free agent at Tuesday's 4 p.m. deadline -- the official start of free agency.

Winslow, 30, is set to become an unrestricted free agent, while fellow tight end Konrad Reuland will be a restricted free agent. It's widely assumed the Jets will not re-sign Winslow, but the team also has Zach Sudfeld, Chris Pantale and Colin Anderson (reserve/future) on the roster. The Jets still are expected to scope out other tight ends.
