Rambo, 27, is a former sixth-round pick of the Redskins back in 2013. He lasted just over a year in Washington before he was waived at the start of the 2014 season.
Rambo later caught on with the Bills towards the end of the 2014 season before joining the Dolphins midseason last year. Buffalo re-signed Rambo back in July.
In 2016, Rambo nine games and recorded 42 tackles, one interception, and three pass defenses.
Rolle, 26, originally signed on with the Bills as an undrafted free agent out of Catawba back in 2013. He lasted just a few months with the Bills before joining the Saints and Packers for brief periods of time.
The Texans later signed Rolle off of the Packers’ practice in October of 2015 and he managed to make the 53-man roster that season. However, Houston elected to cut him loose midseason to make room for QB Brandon Weeden and the Ravens later added him to their practice squad in November.
The Ravens brought him back on a one-year exclusive rights contract last year and even tendered him a restricted offer this offseason but later rescinded the deal back in March. Rolle signed on with the Cardinals a few weeks after this year’s draft, but was waived a few weeks ago.
Unfortunately, Rolle suffered a torn Achilles last year and subsequently missed the entire 2016 season.
Ross, 26, originally signed on with the Titans as an undrafted free agent out of Arizona State back in 2013. He had brief stints with the Chiefs, Redskins and Bears before returning to Washington during the 2014 season.
Ross has managed to make the 53-man roster in each of the past two years with the Redskins. However, he was cut loose by Washington back in December and later added to the Lions’ practice squad.
The 49ers signed him to a future/reserve contract this past January only to cut him loose a few months ago. The Bills signed him to a contract in June.
In 2016, Ross has appeared in five games and caught one pass for eight yards receiving and no touchdowns. He has also contributed 22 kick return yards for Washington this season.
