Gronk wears 69! Woooo, Just kidding, but come on, its the perfect number for Gronk.
On a serious note, the following players wore #69 for the Patriots:
Julius Adams 1987
Eugene Chung 1992-1994
Ross Tucker 2005
Alex Silvestro 2011
Kyle Hix 2012
Shaq Mason 2015-2017
No Steelers player wore number 79 in 1992. John Rienstra wore the number from 1986 to 1990. Then James Parrish wore it in 1995.
In 1972, outside linebacker Jack Ham wore #59 for the Steelers.
Wade Griffin
No one.
Santana Moss is number 89 on the Washington Redskins.
89
Mark Bavaro - Giants
I would say a small number of times. The Lions record against the Packers entering 2011 is 65-89-7.
No one has worn number 89 during a regular-season game for the Yankees.
Two tight ends wore #89 during the 1970's for the Steelers. Bennie Cunningham wore the number from 1976-1985 and John McMakin from 1972-1974.
Mike Ditka wore #89 with the Bears, Eagles, and Cowboys.
Tight End Mike McNeill wears it now.
Chris Hanburger, one of the greatest, and maybe his number should have been retired, but after that I think either Mel Kaufman or Monte Coleman had the same one. ---- Coleman wore #51. Kauffman wore #55. Also Andre Collins wore #55 for the Redskins. For the 2008 season, #55 will be worn by Jason Taylor.
Mike Ditka had 2 different numbers during his time in Philadelphia, in 1967 his jersey was #98. In 1968 his jersey number was #89.
Billy Joe Dupree wore #89 jersey in 1978
Tony Martin wore # 89 for the 1992 Miami Dolphins.
