LSJU has done nothing to indicate they are anything special, not in non-conference, and not in conference. In conference, they beat Cal at home. If they can't do that, they are really crappy. They swept the Washington schools at home. Um, yeah, so did Cal, and both had the advantage of playing UW right after they lost their point guard for the year. And after having 2 of their first 3 wins against 2 of the bottom 3 teams in the conference, they won a road game against the third of the bottom 3 teams in the conference.
A middle of the Pac team should be 4-0 against that competition right now. If LSJU wins on Saturday, it might be time to say, "Oh, crap, LSJU might finish toward the top of a crappy conference. As opposed to toward the bottom of a crappy conference like Cal."
This ain't Monty's LSJU team. They appear mediocre at best. The problem isn't how good LSJU is, the problem is how crappy Cal is. If Cal could rise to being mediocre, we'd be pretty evenly matched with LSJU. If we can rise to being good, we'll beat them most of the time. Those are BIG ifs. But I don't think we need to worry about LSJU, we only need to worry about Cal.
