It's not reviewable, as Royce Young and Ty Lue say in the tweets posted two pages ago. He's 2' outside the arc...and he was actually never inside it, either.
12. Restricted Area Block/Charge
Referees may review block/charge calls when they are not reasonably certain as to whether the defender was inside or outside of the restricted area during the last two minutes of the fourth period and overtime.
Two refs had unimpaired views of the restricted area. One of them has the job to look for that.
It's like checking a 27' three pointer to make sure he was behind the line. Not close. So weird that Mike Breen says he's in the restricted area.
