Ever hear of Mark Texiera? He did the same thing when the Red Sox came a calling his senior year in high school. They called the night before the draft, said they would give him 1.1 mil. to sign. He thanked them but declined. They drafted him anyway in like the 8th round. He went on to Georgia Tech, had a great college career, was drafted 4th overall after his junior year (got a 10 million dollar signing bonus - thanks BORAS), and appears on his way to a terrific career.
Maybe the players know something about the RedSox that the rest of us don't?
