Looking at the list of official visitors, something that jumps out to me is the number that are currently committed to Nebraska (23 commits of 44 visitors, 52%). The numbers go up a little if you include all that have committed, even those that have subsequently decommitted, i.e., Waz, Clinkscales, and Slade (26 commits of 44 visitors, 59%). This does not include the four that are currently on an official this weekend at Nebraska, all which have been thought to be highly likely to commit as of recent. Also, of the 44 that visited, four have not committed anywhere yet (though only two are still considered possibilities, i.e., Frison and Brown, both which are also considering ASU).
Here is the official visitor list:

We say getting them on campus is critical to the recruiting game. This just confirms that line of thought, especially if you consider the number of offers that have gone out (~350), and the fact that only one recruit, Jason Hall, has committed this year who did not take a visit at some point (unofficial or official). In that department, we are 1 commit of ~306 offers.
I will concede that the data could be skewed because if a recruit takes an official, chances are his interest is already rather high. This is also evident in the number of guys that take unofficials, visiting on their own dime (which shows they are highly interested), who eventually get a Nebraska offer (13 commits of 19 visitors, 68%).
