I'm not going to try and predict every game from now to the end of the season. But, after looking at the schedule, I think there are some logical paths to a bowl for six C-USA teams.

Marshall (4-2) Still hosts S. Miss (0-6) and plays at FIU (1-5)
ECU (5-2) Should get bowl eligible at FIU (1-5)
Rice (5-2) Hosting UTEP (1-5) next
Tulane (5-2) at FAU (2-5) and hosting UTEP (1-5)
North Texas (4-3) At S. Miss (0-6) and hosting UTEP (1-5)
MTSU (3-4) Finishes the season against FIU (1-5), at S. Miss (0-6), and hosting UTEP (1-5)

Tulsa could make it to a bowl, but it doesn't look likely to me.

Tulsa (2-4) With these games left...@ Tulane (5-2), UTSA (2-5), @ ECU (5-2), Marshall (4-2), @ LA Tech (2-5), North Texas (4-3)

4 wins in those 6 games won't be easy.
