Yes, but I don't really know what you're getting at. True, a good seed means you're favored to win a game or two (or more for a top-4 seed), but that speaks to the over-arching point of "we're usually pretty good."
Found a Wikipedia list of all our NCAA Tourney seeds here, in case anyone's interested: https://en.wikipedia.org/wiki/Illinois_Fighting_Illini_men's_basketball#NCAA_Tournament_seeding_history
