Lack of a ring did Owens in. If you eliminate Owens last two seasons giving him the same number as Harrison, they match up pretty closely. Looking exclusively at talent I'd take Owens. If I was a GM trying to win a title I'd take Harrison. They probably should have both gotten in but Dungy likely pushed Owens out. Owens is a mortal lock next year.
Except he's not because I think Moss is eligible next year. And I could see Moss
POSSIBLY jumping TO and also for reasons I'll explain below.
That said, on local sports radio here, one of the writers here who votes each year for the HOF explained why TO may not have gotten in. Guys like Holt and Bruce are also eligible and it's very possible that TO will have to wait his turn. The explanation given was that these guys are all HOF worthy and they used to get NONE of these guys in because the votes would constantly get split when they went up against each other. So they formed an unwritten rule that the guys just went in one at a time, in turn, to clear up the logjam. So even if a guy like TO is otherwise more worthy in a vacuum, since these other guys have waited, they'll likely get in first and TO will just have to wait his turn.
It's not ideal, but he makes a good point. Prior to doing it the way they do it now, none of these guys were getting in because some argued for Harrison, some argued for Holt, some argued for TO and none of them got enough votes to make it in.
