One thing to keep in mind about Flowers is he is not 23 or 24 years old. I think he is slightly older than Gordon Beckham, so everyone who thinks Beckham can't get better, shouldn't be thinking Flowers is going to suddenly improve offensively. Defensively, if he becomes the regular, it will be interesting to see how he holds up playing more often. He could be fine, the increased workload could work against him.
The thing that really concerns me offensively besides his lack of contact, is he has been very slow with adjustments. They find your weaknesses fast at this level, and he is going to have to fix that.
