Reiss does a lot more than reporting. He has a weekly mailbag and a weekly chat where he offers up his opinions, additionally, the blog has started updated with videos of his analysis. That's the key word, he provides analysis, yes it's his opinion, but he has no agenda. No one will turn on him b/c he's too reasonable and fair.
Cafardo's, Borges', Felgers, etc., these guys want attention, they want their opinion to stand out, and in some cases, are just bitter old coots. Reiss has earned the fanbases respect, and I don't think he'll lose it any time soon.
