re: New professional angle clearly shows line judge reaching for flag

My understanding (at this point I am not sure where I got it) is that #60 the side judge called a tip and that's why #13 held the flag. #13 would have deferred on the tip call since the SJ had a better view of the LOS. It is all on #60. However, #13 should have called the penalty and conferred with those closest to the line to determine if there was indeed a tip and picked up the flag if warranted.
