Columbia has an excellent coaching staff. Our son took an official visit and has now played against them for 2 years. Brett Boretti likes his players to be very aggressive, confident, supportive of teammates, always "on". I recommend telling your son to stand out by being vocal, playing hard and letting his talent show itself. As with all these showcases the coaches will run the players through drills to evaluate the measurables. Boretti certainly will look at the measurables, but after that he wants players who show a lot of passion for the game.
