The quote from the article that doesn't sit well with me is:
"There is only one thing that his critics can legitimately point to that would keep him out of the Hall of Fame: the one stat that actually counts – rings. "
I wouldn't say "rings" are absolutely essential, however, 10 years into his career Romo has only been involved in a single solitary playoff victory -- which just doesn't cut it for HoF -- I don't care what his stats are.
Marino, Kelly, Fouts, etc never won a Superbowl, but they won a lot a ton playoff games, played played in conference championships, and in the case of Marino and Kelly played in 5 collective Super Bowls.
Maybe the one HoF QB outlier that Romo fans could point to in terms of a QB with a <somewhat> similar career trajectory is Warren Moon. He only won 3 playoff games. However, the fact that he was basically denied the opportunity during the 1st half of his career due to his color I believe contributed to him getting in.
Romo does have some time left to remedy all of this. I'm not sure playoffs wins will get it done -- I think he needs a Superbowl victory.
