Better than nothing and I have no idea how different coaches evaluate players, but if they are anything like me evaluating my DD they would need to have a camera pointed directly at the player they were looking at the the whole time
Well, that can be done with other video and scrimmage games rather than going to an "exposure tournament" where there will be no interaction between club coaches and college coaches. Teams pay the expenses to travel to these bigger tournaments because college coaches are there and available. No college coaches, means it is not really an exposure and in turn is technically not meeting the needs of the team.
However, I will say there might be a big opportunity for ESPN here, lol. At this point, I will watch just about anything with a ball on TV, if it is live.
