As a fan of Batherson, why wasn't I excited about him being called up? And, wasn't happy about his extended stay, when he should be sent down a few games earlier?
Him being called up won't hurt his development or anything obviously. But, you are missing the point here. What he was experiencing before him being called up was something special for a 20 year old kid. His dominance and him being in the lime light could go a long way for him, to have that swagger and mentally take his game to another level. I don't see why the organization had to mess with a great thing going on with him. Let him ride that wave would've been the better choice.
Now, all that necessarily doesn't mean anything or wouldn't even matter in the long run, and that him being called up wasn't a wrong decision, but clearly wasn't the best one either, at the point in time.
