The former Miami Dolphins running back joined the Lions during the off-season, recording 90 rushing yards, 101 receiving yards and a touchdown in his first regular season game for the team.
The Arizona Cardinals linebacker, who was teammates with Bush at the Dolphins, told reporters: "He gives them an element they haven't had. He's a dynamic player, man. Always has been. They are finding ways to use him to their benefit.
"It's part of the business, because every back in this league is dangerous. They can break one tackle and take it to the house. He's dynamic, and they use him well."
The Cardinals play the Lions on Sunday.
