The Lions can utilize void years. Holmes has done this in the past but on a much smaller scale. For instance, Bridgewater is going to cost $500k on the cap next year because he has a void year. The Eagles added void years to Hurts contract and the Vikings did it with Cousins. If Cousins signs with another team, he's still going to cost $28 million on the Vikings cap. It's a calculation if the cap is more valuable today than in the future. If you extend the player, those void years wouldn't count. The Eagles are banking on signing Hurts to another extension. Those void years are going to come to roost if they don't.
