Notre Dame supposedly has one of the best networks for it's graduates. However, i'm sure former football players from NU get a lot of doors opened for them also. It's not like he will be the average NU or ND graduate. Acadmecially, he'll only get out of it what he puts into at either place. If he works hard, he can just as good an education at NU as he would at ND, imo. Conections wise, he should be in a great position from either place as well.
This is all moot if Trevor goes to the NFL. On that note, i think ND and NU present about the same opportunity of getting there.
Really, i think whoever said he can't go wrong at either place is right. Both schools can give him a great education (with the possibility of a poor one if he doesn't put in the effort), both give him a good shot at going to the NFL, both give him a good shot of having a career after football if the NFL isn't in his future. Both present about equal opportunity of playing time.
