Actually, I thought KC's example was pretty good. If you followed KY baseball last year, they were a high scoring team that had rather poor pitching. KY signed 10 pitchers in that group of 17 and they look like a good group. 7 position players isn't much in a year. I think Cohen addressed their needs pretty well.
Saying "This is the best class we’ve signed since we’ve been here,” meant since Cohen has been there, which is only about 2-3 years if memory serves. I don't think he was saying it was the best in the country, just the best for KY in the last couple of years (and probably longer since they haven't been competitive lately). Just because this year's class didn't make Top 25 doesn't change his view.
