I'm not really sold the Herman thing was that big of a factor. He's a fan blogger who posted something that was shot down, what, hours later by another blogger/reporter? And then the team itself directly pointed to it and said it was crap? I don't think the other teams around the league would put a ton of stock into something Herman said--he's not even taken seriously by most here.
If there's now interest in him I think it's because other teams have had an opportunity to discuss the situation with the Rangers and run their own intel and are satisfied that, at a reduced price, he is worth the risk. I don't think it had anything to do with the Herman garbage.
