In order for a person to be "polarizing," the public's opinion of them has to be both divided and extreme. They're either loved or hated; the best there ever was or the worst, with little room for middle ground. And while this characterization might have described former Seattle Seahawks linebacker Brian Bosworth 20 years ago, the opposite is true now.
If anything, Bosworth is one of the rare controversial-in-his-day athletes about whom there is now a consensus. That of an over-hyped, injury-prone player as focused on the marketability of his bad-boy image as he was the playbook.
For most polarizing, you'd have to look at a guy like Alex Rodriguez. Beloved during his time as a Mariner, but now hated not only because he makes his millions with the New York Yankees, but also because of his difficulty expressing anything resembling human emotions.
Rick Neuheisel, Dave Krieg, George Karl, Freddy Garcia. Any or all could be considered more polarizing than Bosworth. And for anyone thinking the real answer here is "Howard Schultz" or "Clay Bennet," remember: to be polarizing means having an equal number of admirers too.
