Jenkins' opinion isn't really relevant.
As well as looking at replays in his 23 seconds, is the reviewer also meant to lip read all the players in the area?
What if Jenkins thinks it hit the post, another player thinks it didn't hit the post, another player thinks it didn't even go through the goals, another one has no idea? Which one does he use? Does he do a poll of players? How much weight do the players' opinions get compared with the goal umpire? What about the field umpire or the people in the front row?
