In 1987 the Buffalo Bills introduced a new font to their jerseys—on some of them anyway. The font we became familiar with during the Bills Super Bowl run seemed to be introduced in 1987 and then fully in 1988. The most noted differences were in the "2s" and "7s".
Here is the only example I can find of the "2". It is angeled.Jim Kelly's "2" is square.
Andre Reed (83) has the newer font.
Bruce Smith's "7" does not have a serif on the bottom and Cornelius Bennett's does
Nate Odomes and Ron Pitts have the full block "7" with the serif on the bottom
