Everyone, everywhere rationalizes everything. It in no way is endemic of UL alone to rationalize losses or anything else pegged as a cause or partial cause of things gone wrong. The SBC basketball refs are inconsistent and that lends itself to deserved criticism. Whether UL is always going to be on the short end of that stick is arguable. The ref argument is probably the weakest of all for a legitimate excuse, but it really sucks for them to decide the outcome of games. They definitely need to be more consistent... and make-up calls when you blow a call are perfectly acceptable.
As for youth and inexperience... it can and very often does become one of the largest separators in team sports. Until it is truly not a legitimate issue, it is a legitimate issue. Youth and inexperience is a monumental handicap on almost every team. An occasional "Fab Five" does not make the rule. It is about like the moron who said that WKU isn't a good team. They are not as athletic as UL, but they are a damn good "team". Some of those WKU "lesser athletic players" know more about where to be on that floor and when than most teams in the country.
Granted, eventually the youth become not-so-young, and then they either succeed with experience... or we all have to start choosing other causes (excuses) and rationalizing "them".
But most of all... you should not be asking anyone to "accept the fact that we lost". I hope we never accept the fact that we lost... anything, anywhere, anytime.
