Or maybe they really feel they got the best available players. Their top pick, Trevor Bell, was once considered the best 14 year old in the country. He consistently hits 94, 95 with his fastball and has a major league curve according to scouting reports. He's also put up big offensive numbers, giving them the option of looking at him as a position player.
All that said, there's no doubt in my mind that not being represented by Boras made him even more attractive.
