Do players wanting to get recruited go to ALL of these 3 football camps?

As a high school football coach I can only give you opinions on what I see. Any camp, not matter where, is said to be for the benefit of the players when in reality it is a way for colleges to assess talent on a large scale and little to no cost to their school. All three would probably be good for recruiting purposes, however I would recomend seeing if any of the colleges you are interested in have individual camps. If so, get to them by any means. While you are there work hard and make sure to talk to the coaches. You want them to pay attention to you and remember your name. Best of luck in your future!
