It's very strange that we're in a position to really need CBs, he could come in and play right away, but he takes the Michigan offer. What did they tell him, what did they promise him, and what did we not do correctly? Very weird.
It could be as simple as this --- Michigan is trending up. They play hard, have been winning and their future is bright. They ripped NU last year and, if I were their coach, I'd simply state that NU is not trending up and Michigan is --- and that Michigan has a vastly superior recruiting class relative to NU both this year and last --- so that they likely will be pulling even more ahead of NU with time . Seems, actually, quite a simple recruiting sell. Michigan is upwardly mobile and heading places.
I am not at all surprised that NU loses out to Michigan for a recruit.. they (Michigan) likely would get the player in the vast, vast majority of cases --- for reasons quite clear. We can win those recruiting battles if a special relationship between the player and our coaches arises... and there are legitimate and good reasons to come to NU too. But NU is at a huge disadvantage recruiting against Michigan. We might win some.. but will lose most.
