Rules exist which tie a player's number to a specific range of numbers for their primary position . Additionally, rules exist which limit who may handle the ball on offense, generally players who are designated as offensive lineman, who wear numbers 50 - 79, are not allowed to handle the ball during a play from scrimmage, though they are allowed to do so if they report to the referee as playing out of position . </P> <P> The earliest numbering systems were significantly different from the modern variation . Until the 1920s, when the NFL limited its rosters to 22 players, it was rare to see player numbers much higher than 25 (Red Grange was a notable exception, wearing 77 with the Chicago Bears while playing halfback, which would not be allowed under current NFL rules), and numbers had little correlation with positions (in 1929, the Orange Tornadoes subverted the system even further, experimenting with using letters instead of numbers .) </P>
