The betting in question was at a time in which he was managing the Reds and had already been crowned hit king. Nothing in his stats suggest he didnt play his hardest during his playing days even if he was betting before managing unless you consider betting on yourself to succeed is harmful to one's game... but thats another discussion.
I don't think you can parallel Rose betting as a manager after his record was set with Bond's steroid induced HR chase that he will likely reach.
The biggest problem Rose has is his incrementalism. First, (after over a decade of lying) it was betting on sports, but not baseball. Then it was baseball, but not his team. After that, it was for his team, but only to win. Given the track record of lies, he's not credible. We'll probably get the same from Barry down the road. He stands by not "knowingly" taking steroids, for now. That's likely to evolve into...."Well, it wasn't illegal at the time." That's my parallel.
