Maybe the plan all along was to have A.Q. Shipley be a backup all along and that Lyle Sendlein would be the starting center in 2015.
Sendlein was released n March for contractual reasons -- he was simply going to be paid much more than the Cardinals wanted to commit to the center position. When he was released, general manager Steve Keim said he wanted the four-time captain back.
The team signed A.Q. Shipley to a two-year contract and it was believed he would be the starting center. However, the contract looked like backup money.
