Just because Trent Dilfer is high on Josh Rosen and his ability to handle the New York spotlight doesn't mean he thinks the Giants should draft the UCLA star.

Actually, the sharp-minded quarterback analyst says the Giants are in the fortunate position to pass on Rosen, USC's Sam Darnold, Oklahoma's Baker Mayfield and Wyoming's Josh Allen as the eventual successor to Eli Manning.

Rosen, Mayfield and Allen will throw in front of scouts Saturday at the NFL Combine, while Darnold opted to wait for USC's Pro Day.

"I think they have their future quarterback," Dilfer told NJ Advance Media in a 1-on-1 interview, "given enough time and given that they have a two-time Super Bowl champion to bridge a couple years to integrate that guy in."

Dilfer is referring to a future with Davis Webb, the second-year pro who inexplicably took zero regular-season snaps as a rookie during a 3-13 season.

Webb was drafted in the third round last April by a regime - general manager Jerry Reese, vice president of player evaluation Marc Ross and coach Ben McAdoo - no longer in place. All were fired in December.

"Giving Davis a year or two more to develop and learn the ropes and kind of establish himself in the locker room and play well in preseason, it helps your team," Dilfer said. "Now you don't have to go overpay at the position, or draft and roll the dice."

The Giants already have named Manning, 37, the starter for 2018. Though the NFL has restrictions on coach-player interaction at this time of year, Manning quickly got to work studying new coach Pat Shurmur's West Coast offense.

Had the Giants been a .500 team drafting in the middle of the first round, Webb's place as next in line to Manning might be more secure without any more or less of a contribution from him.

But because the Giants hold the No. 2 pick - their highest since 1981 - the temptation exists to draft a top quarterback to leapfrog Webb.

"I really like the combination of Eli and Davis Webb," Dilfer said. "I might be on an island there, but I think Eli still has a lot of good stuff in the tank.

"Especially considering so much of this game now is from the neck up. Eli has plenty of talent, plenty of juice. He just needs more answers to the test. He needs to be able to win the game intellectually as much as physically. I think this system will allow him to do that."

Mike Shula is the new Giants offensive coordinator and quarterbacks coach, filling two jobs held last season by Mike Sullivan and Frank Cignetti, respectively.

In addition to coaching Panthers star Cam Newton to a NFL MVP award, Shula has pulled career years out of Dilfer, David Garrard and Jay Fielder.

"Webb had a really good quarterback coach in Frank Cignetti, who I know taught him a lot of processes: How to study, and watch, and go about your business," Dilfer said.

"I think Mike will build on top of that. I think the real benefit to Davis is he will learn the teaching progression of the West Coast (offense). They literally start from scratch every camp."
