Fenway Park

[BoomerSooner]

I just saw the preview of the Notre Dame vs. Boston College game being played at Fenway Park and they commented on both teams being on the same sideline. Obviously there are all kinds of logistical issues the officials will have to adjust to for this game, but I'm curious to see how substitutions work. Specifically, I'm interested to see how matchup substitutions will play out when the defense is on the end of the field opposite its own bench. Based on my understanding of NCAA rules and mechanics, the offense won't be able to substitute with less than about 15 to 20 seconds on the play clock because it could take them 10-15 seconds just to run a substitute in or off the field if a 300 pound D-lineman has to run 60-70 yards off or back to the bench. In this scenario the crew should prevent the snap until the oncoming sub has time to get into position and the outgoing player has had an opportunity to make it back to the bench. My thought is that it could take the sub 10 seconds to get to the opposite end of the field and even if the outgoing player realizes he is being subbed for when that player is halfway downfield (5 seconds), if he takes the same 10 seconds to run off that is a total of 15 seconds.

Anyone have any thoughts on this or heard any details on adjustments being made by the officiating crew for this game?
