As much as I hate to admit it, Alzado probably swung both ways. There were a ton of old times at Gold's that swore that he enjoyed the company of guys sometimes, and that no one said anything because Lyle was genuinely nice guy, and they didn't want to embarrass him.
Matuszak never had any gay rumors about him, but he did do a Playgirl spread or similar that was hugely collectible with the bears.
