From his birthday until today, is 85-days....
*Consider the Bengals are in the AFC North, with the Steelers, who are in their 85th season.
*Consider Marvin Lewis was hired after the Rooney Rule, named after Dan Rooney, who died 98-days before his 85th birthday, before the NFL's 98th season and Steeler's 85th.
It has been 8-months and 5-days since Dan Rooney died.
As for him going out at 59...
Also, with regards to coaching 15-seasons, 47 is the 15th prime.
Today's date also has numerology of 66. 12/17/2017 = 12+17+20+17 = 66 (NFL = 66)
Later today the Bengals play the Vikings, who are hosting Super Bowl 52 this year.
