"It's been too close to call," Lee said. "I want it clear. I want it cleaner before we make that decision."
Lee also acknowledged that he has often gone back and forth on who he thinks the starter should ultimately be.
"They come off the field and you're frowning at one and (saying), 'Atta boy' to the other," Lee said. "I'm being honest, it's kind of been an emotional up-and-down deal: 'Who's the best one today? Maybe that's our guy. We can do this with him and the other one, we can do this with him. We can do more with this guy in the passing game.'
"So that's an honest answer."
Mornhinweg insisted he hadn't put as much thought into the daily fluctuations of the quarterbacks, preferring to let everything play out.
"Mark has had a terrific camp," Mornhinweg said. "He's had a bunch of ups, and he's had some dips there. Geno's had an outstanding camp for a rookie and he's just had a little bit more than a couple of plays in a preseason game. So, we'll see what happens in this next ballgame. We'll see what the outcome is."
Ryan also refused to put any parameters on what Smith might need to show against the Giants to be convinced that he's the guy who should start the season under center.
"I think obviously it's an evaluation process still that we're going through," he said. "I don't want to say, 'Look, he's got to look like Phil Simms in the Super Bowl.'"
That performance by Simms, of course, was one for the record books when he completed 22 of 25 passes to help the Giants beat the Denver Broncos in 1987.
Mornhinweg said the decision will be made when one of the quarterbacks elevates himself above the other, and if that doesn't happen, the team would then go on instincts.
"I think I know exactly where Mark's at," Mornhinweg said. "There's no question that I think we can do some very good things with Mark. I don't quite know where Geno's at yet, even though we might think we know. But those preseason games are such a good evaluation period for a young man."
NOTES: Lee revealed that Sanchez recently had minor surgery to repair an infected toe nail on his right foot. "He doesn't blink, he doesn't tell me, I just happened to hear from somebody else," Lee said. "He's out there, practices." ... Ryan announced that Vladimir Ducasse will start at LG against the Giants instead of Stephen Peterman, who is getting work at center to back up Nick Mangold.
