Regardless of what you think of PBR or for that matter any scouted event any coach who bases his selection solely on a 60 time 10 swings and fielding a handful of groundballs or flyballs won't be in his position for long. The best thing I can advise is have your boy on a good travel team that will give him exposure to college coaches, for example TopTier, Sparks, Longshots etc. where coaches can see your boy in a game situation. Combine this with camps where schools you have a genuine interest in sending your son to will be in attendance so that they can get a closer look at your player. Doing these two things will get your son the most exposure and hopefully a ride to a school.
