You're very much in the minority about Betts. He tore up both AA and AAA before an impressive stint with the big team. His bat speed and his quickness are the real deal. Obviously it's no sure thing yet, but this kid is an exceptional prospect.
Trading for Hamels is a double-pay, because you have to lay out $110 million, plus prospects. And we don't know how well he'd transition to the AL. His interleague numbers against AL teams are not good.
