One of the most important lessons learned from the Arizona Cardinals last season is that having quality depth is equally as important as having a quality starting lineup. They can never have enough depth.
And they learned that the hard way with the unexpected retirement of Malcolm Butler that offseason and the injuries to both J.J. Watt and Robert Alford midway through 2021.
The Cardinals caught fire with a 10-2 start but came crashing back down to earth with a 1-5 record the rest of the way, which includes the 34-11 blowout loss against the Rams in the Wild Card round of the NFL playoffs.
