NFL Rules Changes 2017: Overtime, Touchdown Celebrations, Roster Sizes Affected By New Guidelines

Still more than three months away from the start of the 2017 season, the NFL has decided to make a few rule changes. Overtime, touchdown celebrations and the manner in which teams trim their rosters down during training camp will all be affected by the new rules.

Perhaps the biggest move made by the NFL owners Tuesday was the decision to make overtime 10 minutes. The extra period had previously been 15 minutes, the same length as all four quarters.
