Yes it was dumb for him to say that he was going to steal 60 bases. Especially when he wasn't even a lock for a starting job. At this pace now, he'll be lucky to get 15-20.
Sandy is going to be a great coach someday, I have no doubt about that. As far as Ben Davis, I've noticed whenever I watch he's pretty strikeout prone. Not a Joe Borchard strikeout prone, but he takes a seat pretty often though.
Rowand better be either 1 or 2 for the rest of the season. I'd prefere him at 2 but right now there is nobody worthy enough to be lead off so it should be his.
I'm sure there will be plenty of time to talk about this in the offseason, but now that it's mentioned, yes, give him a shot at it. He may have a good year left in him.
