To be fairly answer your question you would have to interview each recruit to find out why they choose another school over ND. We would just be guessing otherwise.
Interesting statement Marcus Freeman made when asked about his recruiting. He said something to the effect that it’s hard work and it takes a lot of time. That you have to build relationships with these guys that takes a lot of time. Because of that you just couldn’t offer everyone. Well based upon the numbers of offers it looks like Kelly is willing to spend twice as much time trying to build relationships then his previous regime was willing to do...
Yeah, some of this is really tough to answer. We do know that Weis had a determination that he would chase the top 100 type recruit all the way to the end, even sometimes at the cost of other primary targets that were more of a 4 star or high 3 star, and sometimes ended up with absolute emergency type takes. However, by staying in on those guys late, he got a lot more of them.
I don't necessarily know the setup of the recruiting office, but Elston and Freeman both made comments along the lines of "can't expect the head coach to text everyone 6 times". But shouldn't we? Even if it's a recruiting intern with "coach Kelly's phone" following him around and quickly typing out some texts to communicate? Granted, ND is proud of how much money the football program sends the university each year, and adding administrative costs like deeper staffing in football support positions would hurt that, but if ND had a championship this decade, wouldn't that pay off?
