Refs will penalize players who dunk over the goal post
NFL head of officiating Dean Blandino told the Dan Patrick Show that starting this season, dunks will be a penalty. Tthe NFL has a rule against using the ball as a prop, and apparently that’s the rule that will be used to ban dunks. So it’s not a new rule, it’s a new interpretation of an existing rule.
The goal post dunk became a concern when Saints tight end (or wide receiver) Jimmy Graham knocked the goal post askew while dunking in Atlanta. The NFL is also considering making the uprights longer, which would make them more top-heavy and therefore potentially more likely to fall over entirely.
