I mean UCF really is not a very good loss.
While I don't like that we're out of the top 5 where we belong, we have arguably the worst loss of any currently ranked top-10 team.
Cuse hasn't lost and has shown that they (at this juncture) have the strongest depth in the country; OSU lost to a solid KU team without their far-and-away best player; UK lost to Indiana in a crazy environment at the buzzer (and IU is certainly better than UCF); Louisville is 4 simply because of preseason hype and the fact that they haven't lost yet (although their wins include against Memphis away from home); UNC lost to now-ranked UNLV (still better than UCF) in Vegas and by one visiting UK while having wins against decent teams (now-ranked but stll overrated MSU and Wisconsin); Baylor is lossless (but hasn't played anyone and will not be in the top 15 by the end of the season); Puke has only lost to OSU; at least for the coaches poll: Mizzou hasn't lost either (but has only beaten Cal, which is hardly a big deal) and shoots really well from the field thus far.
