Again KB, if you do not believe that you can sign your top pick, you do not make the selection. It would have been a waste of the pick.
As far as Hochevar goes, he was dealing with different rules back then. They did not have the caps on draft spending then, so you cannot really compare the two situations. If Appel were to go play in the Independent League, he would still have the same range of money to play with next season. He would have wasted a season of decent salary...unless he really doesn't want to pitch for Houston if they pick him.
