Unfortunately, no. It is the home team's responsibility to have 36 footballs, 24 for indoor games, ready to be checked by the head referee, with a pressure gauge, two hours prior to the game. Those balls must meet the NFL's requirements or they will not be used. Also, twelve new footballs, sealed in a special box and shipped by the manufacturer, will be opened in the officials' locker room two hours prior to the starting time of the game. These balls are to be specially marked with the letter "k" and used exclusively for the kicking game. Does that help?
I heard on FOX Sports yesterday that an NFL game starts with 36 footballs. They also commented that a rookie quarterback may have a hard time adjusting to the use of new balls in the NFL as opposed to college play. (Never heard that before yesterday)
1. Leather FootballsLeather footballs are the highest grade footballs and are typically used in game and practice play. Many of the leather footballs are made with a tanning process that makes the ball tacky, so it is easier to grip, particularly when wet. Some leather footballs are also made to resist absorbing moisture, so they can be used in all weather conditions. Leather footballs that are not specified as water proof or water resistant should not be used in wet conditions, as the ball can absorb water becoming heavier and harder to grip. Leather footballs are only intended for use on grass or turf surfaces.2. Composite FootballsComposite or composite leather footballs are made from synthetic leather. These balls tend to cost less than leather footballs. Composite footballs may be used in game or practice situations and are great recreational use. Composite footballs look and feel like leather, but tend to resist moisture better than real leather. They are also often easier to grip, because the composite material usually has more texture. Some composite leather balls have enhanced the grip of the ball even more by making the cover tacky and/or softer. Composite leather footballs tend to be more durable than leather footballs. However, like leather footballs, these balls are generally intended for use on grass or turf surfaces.
