Florida State's depth issue at quarterback has been a hot topic of conversation.

As it stands at the moment, the Seminoles have two scholarship quarterbacks for spring practice in redshirt sophomore James Blackman and redshirt freshman Jordan Travis.

However, Blackman, who wears jersey No. 1, is the lone scholarship quarterback available for the 2019 season. Travis, a transfer from Louisville, will have to sit out the season if he's not granted a hardship waiver by the NCAA to play this season.

One is indeed a lonely number.

But that's where FSU finds itself after the dismissal of starting quarterback Deondre Francois last month and coach Willie Taggart''s failure to add a quarterback in his 2019 recruiting class.

Barring the addition of either a grad-transfer or junior-college quarterback, many fans are wondering if disaster were to strike, who would FSU turn to after Blackman?

Walk-on quarterback Nolan McDonald is the likely answer.

"He’s a playmaker," Nolan McDonald's brother and FSU tight end Camm McDonald said.

"He’s one of the most dynamic playmakers that I’ve ever played with in my entire career. When the ball is in his hands he’s liable to tuck it and run and go score from any position on the field. He can throw the ball to any position on the field. He can place the ball on the dot 15 yards down the middle of the field or 60 yards down the field to the perimeter.

"I feel like he’s a complete quarterback. But he doesn’t have an issue waiting his turn either, and he knows that it’s James Blackman’s time now. I feel like he’s got a lot to give Nole Nation."

Nolan McDonald isn't a normal walk-on.

He is a former three-star recruit from Long Beach Poly High, one of the premier high schools in California.

He threw for 1,227 yards with 13 touchdowns and two interceptions as a senior in 2016. He also rushed for 349 yards and three touchdowns.

He's listed at 6 feet 2 and 185 pounds.

"He’s a great player," FSU wide receiver Keyshawn Helton said. "He can run and throw. He’s an athlete really."

McDonald signed with Air Force to play quarterback, but he didn't enjoy being there according to his brother. He left before he ever played a snap.

When Camm signed with the Seminoles, Nolan decided to join him as a walk-on.

"Growing up we both knew that we wanted to play college football, but it wasn’t really a big possibility that we would end up at the same school," Camm McDonald said.

"The fact that it happened is crazy. That’s something that I thank God for every day. Coming to Florida from California is a big culture shock so having someone that’s been with you your whole life and really been your best friend your whole life move with you is a blessing. I couldn’t really ask for more."

Nolan McDonald hasn't seen the field yet at FSU. However, he became an internet sensation last fall when a play he made in practice was posted to Twitter.

McDonald made multiple defenders miss and cut back across the field before outrunning the defense to the end zone.

It was a very similar play FSU receiver Peter Warrick made against Louisiana Tech in 1999, though McDonald did it against reserve defenders in practice.

"The play didn’t really shock me because I’ve seen him make plays," Camm McDonald said.

"We’ve been on the same team so many times throughout our careers. He’s been making plays like that his entire career. When I saw people reacting to the play I was like, ‘Now people are finally trying to give him some recognition to see what he can really do.'

"I feel like he has to have an outstanding spring to make himself a little more solidified, but I feel like the video really helped him stamp his place on the Florida State football team right now."

Nolan McDonald was the third string quarterback for FSU during the 2018 season and worked with a lot of the young receivers on FSU's roster.

He earned their respect, as well as the respect of the FSU defense, as the scout team quarterback.

"He’s a scholarship type of guy," FSU cornerback Asante Samuel Jr. said.

"But some things happen and some people don’t get the same chance. He could easily start at another Division I college. He runs the ball well, he throws it well. He’s just like an athlete, a natural-born athlete. It just comes easy to him."

He also fits what FSU is looking to do at the quarterback position under new offensive coordinator Kendal Briles with his mobility.

Starting Nolan McDonald wouldn't be an ideal situation for FSU, but if it comes down to it, he could be a capable back-up.

"I'm probably the most confident out of all of 'Nole Nation (in him)," Camm McDonald said.

"Being that he's a walk-on, a lot of people don't really know what he can do yet. I feel like our coaching staff doesn't really know what he can't do yet because he hasn't been thrown into the fire. They probably do somewhat because they've seen him play...

"I just feel like he's going to be very dynamic in this offense. He's just going to put up big numbers and everybody's going to love him by the time he leaves Florida State. It's gonna be a great story."
