LZ is pretty good, but he's looking more like the exception than the rule.
I wanted to add that LZ is the only one that treats covering the Texans like all NFL teams should be covered. I might not always agree on his analysis, but he tries finding out information, and talks about strengths and weaknesses. If he jokes about the team, it isn't lame punchline humor, it is more specific to what are issues with the team--like the propaganda machine with Texans Pravda, or the time he clowned the way the Texans were making the defensive linemen run in and out of games at the beginning of the 2006 season.
But LZ, is just a blogger for the Chronicle and contributes to the fantasy football stuff in the real paper. What the Chronicle doesn't get is that there are a bunch of national people who follow the Texans, if just for fantasy information. Writing puffy right brained pieces about the team isn't filling that information gap.
