The NFL approved several new rule changes at the owners’ meetings in Arizona last week, including adding No. 0 as a legal number for non-linemen this season.
Before the NFL implemented stricter number rules in 1973, center Jim Otto (No. 00) and quarterback Johnny Clement (No. 0) were among the players who sported zero and double-zero numbers. Players will now once again be allowed to wear No. 0, but not No. 00.
