The trade will fill a major hole in the Rams' secondary after the team traded away Pro Bowl cornerback Marcus Peters to the Baltimore Ravens for linebacker Kenny Young and a fifth-round pick earlier Tuesday.
The Rams' series of moves to address their secondary came after the team placed fellow starting cornerback Aqib Talib on injured reserve because of a rib injury, leaving the team scrambling to shore up its defensive backfield.
Ramsey's four-year tenure in Jacksonville had a rocky conclusion, which ended with the All-Pro defensive back asking the team to trade him after he was chastised by Jaguars executive vice president of football operations Tom Coughlin following a Week 2 loss to the Houston Texans.
Ramsey also got into a verbal altercation with head coach Doug Marrone on the sideline during the Jaguars' matchup against the Texans. The cornerback missed multiple practices and three consecutive games for a variety of reasons, which included an illness, back soreness and the birth of his second child.
Ramsey is in the fourth season of his five-year rookie contract. Through three games this season, he has recorded 17 total tackles, one pass defensed and one forced fumble.
