Ian Book is used to being overlooked despite playing on the big stage at Notre Dame.

That will continue in the NFL after the diminutive Book was selected in the fourth round of Saturday's NFL draft by the New Orleans Saints.

Book stands just 6 feet tall, which is on the small slope of NFL signal callers. But the Saints had a small-size quarterback for the past 15 seasons in legendary Drew Brees, the sure Hall of Famer who retired after last season.

So naturally, another chapter about Book's height was being written after he went to New Orleans with the 133rd overall pick.

"That's just been the story my whole entire life," Book told reporters of his height after being selected. "I've always had a chip on my shoulder. You know, I'm not getting any taller. And Drew Brees has been able to do it -- there's many other quarterbacks, you can go down the list, that have been able to do it.

"We're different players, but we're similar in stature. And (Brees) proved to everybody down there and in the world that he could do it. And I want to do the same thing, and I just feel like I fit in that system well. You know, those are big shoes to fill, there's no doubt about it, but that's an exciting challenge for me."

Veterans Jameis Winston and Taysom Hill are slated to compete for the Saints' starting gig this season. Former NFL starter Trevor Siemian also is on the roster.

Winston and Hill are slated to become free agents after this season so who knows how Book could fit in, say, 2022.

Book was a three-year starter for the Fighting Irish and passed for 8,948 yards, 72 touchdowns and 20 interceptions. He also tacked on 17 rushing scores and compiled a 30-5 record as a starter.

The 72 scoring passes are second in Notre Dame history behind Brady Quinn, who tossed 95 from 2003-06.

And while Saints coach Sean Payton complimented Book in March, Brees also recently had kind remarks about Book's potential.

"I think his skill set carries over," Brees said, according to The Athletic. "He's an athletic guy who can run and make plays with his legs. I think he's got a bright future."
