I think Lowe is a good writer. Like you say in the OP, he is just good at throwing in interesting little bits of information in his columns. Flannery and Jackie both can write an entertaining column.
Have to shout out Amos Barshad, his article on the Nets and the Celtics at the start of the season for Grantland was outstanding, some of the best sports writing I've read in a long time. Not very familiar with him before that piece but definitely on my radar now.
I loved Free Darko back when that was in full swing. Some of the most inventive and interesting sports writing ever. Just so unique and outside the predictable nature of almost all the rest of it out there. Which is cool because it mirrors a lot of the key ideas of Free Darko (freedom from positions, expectations, traditional ideas of fandom, etc).
At least 90 percent of the writing is very boring, sterile, a formulaic. It's not an easy problem to solve so I don't mean to be too critical because I don't have the answers on how to make a lot of the topics interesting, but yes, some writers really nail the good stories.
Like you guys say, I also hate the "NBA INSIDER" type tone and direction a lot of these writers have. Stein, Broussard, Mannix, etc. All boring writers and their tone is just not fun or enjoyable to read. It's as if it's coming at the reader from some elevated, better than you, position. And yes, "sources tell me" information which is so annoying, I feel like a lot of these guys are just puppets of the agents and GMs.
I think one guy that is absolutely awful, and of the "NBA INSIDER" mold is Woj. His writing is extremely boring and predictable and beyond that he is about as sensationalist as you can be and at every turn panders to popular opinions. He spent years blasting LeBron and as soon as LeBron won a title he wrote the most over the top glowing column. It was actually embarassing to read.
