IW and unknown status of ball

[Reffing Rev.]

3rd & 20+ from A's 20 yard line.
A1's pass is caught by A2 at B's 40 yard line, the defender falls down and A2 has a likely touchdown. However B99 starts throwing punches at the LOS during the pass. The umpire blows an inadvertent whistle and the back judge and line judge disagree on whether or not the pass was caught before or after the whistle. Aside from the obvious ejection for B99 and first round from the U, how would you go about deciding which official to go with?


On the field, LJ was more adamant. Went with his call. If video shows he was wrong. He is beating himself up over 40 yards in a 10 point game. Crew chiefs, how would you pick him up to regroup for next game?
