The Jaguars have sent 26-year old free safety Reggie Nelson to the Bengals for 24-year old cornerback David Jones.  Nelson played in 16 games (14 starts) for the Jags last season and he had 70 tackles and defensed 5 passes.  He played in 45 games (42 starts) in his three years with the Jags and he had 187 tackles, 1 sack, 20 passes defensed, 7 interceptions and 1 forced fumble.  He was a huge disappointment after being a high first round pick for the Jaguars not that long ago.  David Jones played in 12 games (0 starts) for the Bengals last season and he had 11 tackles and 1 pass defensed.  Jones has now played in 33 games (7 starts) in his three years with the Bengals and he has 56 tackles and 7 passes defensed.  I don’t expect that Jones will be anything more than a nickel or dime back and a special teams player for the Jags.
