Wisconsin will probably finish ahead of the other Big Ten teams, although Indiana might again beat them. With a much bigger field the effects of the 4/5 are greatly magnified. Indiana is one deeper than before, narrowing what would otherwise be an advantage for Wisconsin. At Big Tens the numbers will go back down. I do not know if Wisconsin will win, as this meet is a matter of pride, not an objective per se (such as winning Big Tens (and Regionals, since their streak is so long) and then NCAAs). So it depends on how they train relative to the race. The same goes for Indiana.
Both teams (and most everyone in the Big Ten) have the advantage of knowing the course which should help in the crowded confines in trying to figure out where you are in the mega-pack.
Illinois is my dark horse in the Big Ten, but I think they will peak for the league meet at home, so this will be a trial run and they are more likely to be about 5th in the Big Ten.
I am not sure how fast this will go out, although I am guessing that Lalang will push the pace and the front guys might or might not follow.
I am interested to see how Purdue does. In the past they would get killed in such a big field with a lot of guys pretty far back. Now, their pack will likely be further up and not having a star or two will not matter as much as have reliable runs from 4 and 5.
On the women's side, the Wisconsin gals have surprised a little bit and will be on their home turf, so they might do OK, but still will be back at least around 5th in the league and possibly further (based on Regional rankings). Some of the strong runners from the past couple of years have moved on so it will be interesting to see how they look in preparation for the podium at Big Tens.
