Sure the young righty has struggled out of the gate, but will sending him down to Triple-A do any good?
Play the kids! Need youth! It's funny how sports fans will sometimes be blinded. Everyone is out to be a General Manager, and they have the best ideas to come up with a championship winning recipe. Sometimes they'll be right, and sometimes they'll be wrong. Such is the nature of sports.
Now I'm not talking about the obvious decisions like "Bryce Harper would make a better starting right fielder than Lyle Overbay" statements, but it's more how people come up with "intricate" solutions to obvious problems on the field.
