Seriously, this isn't that far-fetched of a claim. All Heisey would have to do is play regularly for one full season to get 500 AB. But again, I don't think Keri is saying he is the best thing since sliced bread. He's just saying that he's not as much of a step down from Ludwick as conventional wisdom might suggest. And that the Reds, therefore, have enviable depth.
I understand you want to paint Keri as a cocky "national media type" who knows nothing about Reds baseball. But if you read his writing, he's really nothing of the sort. At least not in this article.
