I don't know that career ending injuries should count against a class. It is what it is. Transfers OK, sometimes they aren't a good fit for the program.
I think starting status is relevant even if the depth of the program is terrible. It shows they aren't a complete recruiting whiff, even if they are the best of the worst. In terms of class quality, it was one of Bronco's best. That's not to say that it's a great class. It's a good class, because there aren't very many whiffs.
