I think the move to the big 10 should have occurred as soon as the big 12 was formed. Nebraska just fits into the big 10.
The benefits are huge both in sports and academics. Also, as previously mentioned, the big 10 network will only aid in recruiting. (Especially in BBall and Football)
add in the natural rivalry with Iowa and the past history with Iowa State, Kansas/K State and it places NU in a very high profile position. The media will watch as much as the fans do. Nationally, there will be a split on those who want NU to have success and those who will rejoice with every loss. This, if played right by the coaches, is a very strong recruitment tool. (Tell/show the recruits the media and exploit the haters. Come here and you'll be seen by everyone. More television, more high profile games etc. Exploit it much like the hated Yankee's have for years.)
Do I expect to see immediate success? No, I expect the weight of leaving old traditions to creating new traditions wearing heavily on the youth who play the sport but in time (3-4 years), I think many fans in Big 10 (especially OSU, Michigan, PSU) realizing that NU is more then talk. Our athletic program, fan base and alumni are proud. We support our University with a vigor that few institutions can match and we (the fans) do truly consider ourselves a intricate component of the athletic program. When our boys/girls step on the field of play we (the state, the fans, alumni) step on that same field with them.
Additionally, Nebraska has long been considered one of the top venues in "all sports" mostly as a result of their hospitality and respect of others. The Big 10 universities embrace and mirror this as well. Rivalries exist but so to does respect. Arrogance is rarely seen in the Big 10 and it is such a breath of fresh air...
Huskers will not disappoint. This I can say with absolute certainty.
