Today's number of the day is 57. There are 57 days until the Arizona Cardinals play their 2015 regular season opener at home against the New Orleans Saints.
57 is the jersey number we will look at today, as well.
The current No. 57 is an important player -- outside linebacker Alex Okafor, who broke out last season, in a sense, with eight sacks. Drafted in the fourth round in 2013, he played only a handful of snaps his rookie season before an injury ended his season. He started the 2014 season banged up, but managed to lead the team in sacks.
