In the end, the top 48 or so programs in P5 conferences are going to separate themselves from the current P5 bottom feeders. That's when the G5 will be completely changed. The top programs in G5 conferences will join up with the former P5 bottom feeders to form a new G5-Series II. The current G5 bottom feeders will be relegated back to FCS.
Now, if UL isn't included in the new G5-Series II group, then that'll be the end of Cajun football.
Right now, I'd say the odds of being included in such a realignment look like this:
In State
UL 75%
ULM 0%
LTU 85%
Tulane 85%
In region
UH 100%
USM 100%
Rice 85%
USA 65%
Ark St 75%
UNT 75%
SMU 100%
TX St 25%
UTSA 85%
Troy 50%
