Chip Kelly's latest experiment involves two Eagles offensive players trying their hand at defense.

Eighth-year wide receiver Jason Avant and fourth-year tight end Clay Harbor have been taking additional practice reps at defensive back and linebacker, respectively, according to The Philadelphia Inquirer's Zach Berman.

Neither player is making a full-time transition. Instead, both are attempting to add versatility, a Kelly staple, in order to increase their chances of making the roster.

Harbor, who has just 47 receptions in three seasons, appears to be on the fringe after the team signed free-agent tight end James Casey and drafted Stanford's Zach Ertz in the second round.

Avant, on the other hand, has been a veteran fixture in the slot for Philadelphia over the past several seasons. He was the team's fourth-leading receiver last year with 648 yards on a career-high 53 receptions.

During his first round of offseason workouts, Kelly has already infused the team with a music playlist during practices and a healthier cafeteria menu.
