You can bet Coppy has forgotten more about baseball, than we will ever know....he doesn't know how it will turn out and neither does anyone else.
He is again and again taking taking a chance on high ceiling guys. Only one or two have to "hit" to make it worth it.
They like DPet much more. There is a gamble both ways of course. Mallex can come out on fire OR (just as likely), he could regress or stay hurt.
Big leftys that throw 95 plus are a rare find. He's only 20. Mallex is 24. If he doesn't progress quickly from here out, he has a tough road ahead.
Everything...everything is a gamble. The most "sure thing" prospect can blow out a arm. The Cuban has lost weight and is getting in shape, if he puts it together...look out. As far as chances go...chances are neither become stars.
One thing is for sure a big young Lefty that throws 95+ will always have more value than a burner outfielder with very little pop in his bat, that doesn't hit for that great of an average either.
The Braves have a ton of talent evaluators, that do this for a living. If they let him go, they don't believe he has much more to show than he already has, and that is....he will never come close to Ender.
