[The Contrarian]

If you are blessed with the talent or skills to distinguish yourself at one of these combines with a blazing 40 time or a lot of x 185 bench reps, (recruiters) are already going to know about you. And if they are seriously interested, they will invite you to their place or time you themselves, not take someone else's word for it. Personally, I would save my money and go directly to any of the various college combines and camps held in or near the state. You are cutting out the middle man. These are business ventures. They primarily promote themselves.

Well said!

I've lived life for quite a few years now, and one thing I remember that was stated to me by a very wise instructor: "Everyone has an agenda, always remember this."

I had posted the above a couple post past, but it is worth repeating, IMO.
The Shulman National Combine is, as was mentioned above, a commercial enterprise, nothing more, nothing less. With the sophistication the recruiters have at their disposal today, they are pretty well aware of the talent out there.
