But I seriously doubt they're too quick on Venters since he has been a Braves guy. They'll likely see the error and weird 9th inning zone and keep him. It'll take him blowing a game vs a LHH for the "talk" and potential let go to happen.
Aggression with prospects is fine, but being stupid is not. There should be a way to find a happy medium between a Pirates like idea of being overly cautious with prospects and going stupidly fast with prospects.
