According to Colts.com’s Kevin Bowen, Indianapolis Colts defensive lineman Arthur Jones has already lost 20 pounds this offseason in an attempt to put less strain on his lower joints:
Art Jones said today he lost about 20 pounds this offseason, wanted to feel lighter on his knees/ankles (battled high ankle sprain in 2014).

Not only will this place less wear-and-tear on his ankles and knees, but Jones will become lighter on his feet and perhaps gain some additional quickness.
