Only Roger didn't qualify anything. He's not talking about regular season only and he's not talking about 'so far.'
"He [Romo] makes things happen. It's a maturing process when you're a quarterback. You know, you've got to take charge. You've got to have responsibility. There are other players who can sure help you with that..."But Tony is a really, really good quarterback, and I think he's going to get better."
He's not saying anything is TBD. He's saying he's really, really good. You should appreciate him, and you're lucky fans that this really, really good player is likely to get better as he matures.
The point is, our HoF QB is giving unqualified praise to a starter who's reputation has taken an unfair beating on the board this offseason. Roger may not be right, but he's definitely giving his input on whether or not it's even worth talking about Tony Romo as part of the problem with this team.
