Jarmon was selected in the third round of the 2009 supplemental draft out of Kentucky. He is 6'3 286 pounds. He was in the supplemental draft because he was declared ineligible for his senior season after failing a drug test.
Lindsay Jones from the Denver Post says that Jarmon was an end in Washington, but is expected to play inside in the Broncos 4-3 system. He also spent time playing outside linebacker for the Redskins
John Elway on his twitter account had this to say about Jarmon.
Jeremy is an athletic defensive lineman with great versatility. We are looking forward to having him as a Bronco.
In his young career, he has played in 16 games, started 1, has 12 tackles and 1 sack.
The deal has financial implications as well - Jarmon will be making $480,000in 2011, significantly less than the $2.4 million Gaffney was due.
Michael Lombardi from NFL Network tweeted that the move is good for both teams because Denver was going to cut Gaffney had we not traded him.
