Those red eye pairings are both terrible. The RDU one is two legs starting early, so not to easy to get sleep. The LGA one is unacceptable. You go from working super late at night i.e. The red eye part to a super early show time the next day. If you sleep right after the red eye portion, you won't be able to easily fall asleep that night. If you wait to sleep until night you'll be a zombie. I know this is how some international pairings work, but those are bad domestic pairings IMO
