Parcells is not being coy. There are several aspects on paper that would seem to be encouraging, but as he will repeatedly tell you, he's got to see it first to be sure.
Start at quarterback. The Cowboys would seem to be better if mere logic prevails; that Quincy Carter improves with experience, Vinny Testaverde gives them a trusted backup and Drew Henson is being groomed for the future.
But . . . .
"I'm not confident at all, because I don't know," was Parcells' response when asked if he was confident Carter would improve this year.
Same with Testaverde. Who knows what to expect out of the 40-year-old quarterback? And he's never even coached Henson in pads.
Just reiterating what many anti QC or those on the fence have to say...
