If you are looking for validation that BC has a better feel for their talent needs and development, how about looking at the Combine invites.

This also doesn't account for other guys who have a good chance of getting drafted even without the Combine (Jeff Smith). BC is finding and developing talent. I do believe that talent wins. I do believe in bigger stronger faster. But these recruiting systems are flawed and not a perfect predictor of anything. I don't trust Addazio with a clock, but I do trust him looking at high school kids and projecting what they can become.
Addazio is also good at managing the roster and is working 5th years right now too. BC's roster will be better than most in the ACC, not the 12th or 14th best.
However, there in lies the problem. BC has all these Combine level players, yet can't win at an elite level. That's on Addazio too. He's a great recruiter and a pretty good developer, but he's not a great coach. At seven years, I don't think that is going to change either.
