Patriots linebacker Ja'Whaun Bentley was flagged for roughing the passer, when there is no element of this play that would make this a foul. The flag was thrown by first-year umpire Duane Heydt -- the referee for the college National Championship game some 354 days ago. Umpires have been tasked in recent seasons to take a quick glance at the contact on the quarterback in case the referee is not in a position to get a clear view of illegal actions. In this case, with the contact in the open field, this should have been sorted out with referee Brad Allen and the flag picked up. The attack is coming toward Allen, so he won't see something on the other side of the quarterback's body.
Bentley made a textbook effort to prevent coming down on Dolphins quarterback Skylar Thompson. He does leave his feet, which is an indicator of launching, but absent contact with the helmet or other forcible contact, we can scratch this off the list. Bentley makes contact within one step of the pass being released, so he's within the envelope of legal contact.
The problem is, a miscall such as this gets thrown into the roughing-the-passer bucket and creates a false standard for fans. It becomes part of the if-that-then-this argument that makes for a difficult acceptance of the rule.
