I can't speak for Arrowryan but IMO its not just the time spent on Robertson. Its the time spent on Robertson, Kelly, McCulloch, Hamlin, etc. If its just Jones that we close with, this will be a poor evaluation at the close of the class. We've had these too many times and its what is creating depth gaps at certain positions.
Also, marginal talent? There are quite a few prospects that I'd take in this class over not having anyone. If you or they decide its marginal, then that's your opinion. I don't view a lot of those guys as marginal and they provide depth to a team that's proven to need it.
I realize there isn't too much they can do as its, kind of, the built in disadvantages of ND recruiting. However, its been quite a few years now where you'd think they start to figure something out.
Again, a good class overall but not even getting to 25 will be poor management of scholarships again.
