Baserunning and some of the errors such as throwing to the wrong base are coaching whether that is Rocco of the minor league coaches I'm not sure. Rocco should attempt to steal more and hit and run more, Rocco basically sits back plays base to base and waits for the HR.
I don't think Rocco is great at managing the pitching staff either. Taking pitchers out too soon and that puts too much pressure on the bullpen. He has to let them at least try to get through 6 or 7 innings sometimes.
I guess he is a "good" manager not great not terrible.
