The BIG is NOT horrible this year. We are one of the top leagues like we are every year (typically we are 1st or 2nd). It is a down year for the BIG because we are missing 2 or 3 teams in the top 10 as we have had in the past. Nebraska is not even close to a top 10 team - so who cares if the big10 doesn't have 3 teams that high because we are going to lose equally to the 10th team in the country as we would the 25-30 team in the country. Now looking at our record against teams from 30-60 in the country would be a good standard and the BIG is not HORRIBLE when it comes to teams in the 20-60 range.
First of all I would argue the BIG was never consistently first or second it was always the old big east(Cuse,Louisville,Pitt,Georgetown,West v,etc) and the ACC battling it out for the top two spots in the recent twenty years, yes u can argue that the BIG won the ACC BIG challenge many times in recent years but that was before they added 3 top programs, not to mention ACC and big east have had more tourny success, and to me now the ACC is clearly on top. The BIG ten on the other hand has one countender this season(Purdue-great big men, average guards, will struggle when they play a team like ucla or Oregon that puts 85 up a game) but wiscy has really been fading and has beaten almost no one.
The middle of the conference is average, but even teams like northwestern have nothing out of conference, and Michigan state had three chances against top ten teams early on couldn't get one, so my point is the BIG is incredibly down if u compare it to any other power conference(yes even SEC).
