The Cardinals' four exclusive rights free agents signed their one-year deals: cornerback C.J. Goodwin, running back Elijhaa Penny, defensive lineman Olsen Pierre and offensive lineman John Wetzel.
Of the four, Pierre has the best chance to be a starter in 2018.
Last year, Pierre played in 14 games with seven starts and was second on the team in sacks with 5 ½.
