He chose a team with an established core of specialists, including a Pro Bowler at his own position: Brian Jennings.
Apparently, McDermott likes a challenge.
"It is rewarding to choose to come to a place and have it work out," McDermott told 49ers.com just hours after hearing the news that he had made the 53-man roster. "I think this is a great organization. It helped that the 49ers are so successful. It made my decision easier when I chose to come here."
Upon choosing to sign with San Francisco, McDermott received a promise that he would be given equal opportunity to compete with Jennings, a 13-year veteran and the longest tenured player on the roster.
"I talked to (special teams) coach (Brad) Seely and he said going into this, it would be a competition," McDermott recalled about his conversation at the end of the draft. "I would be rep for rep, and that's how it was. Coach Seely kept his word."
Seely also provided McDermott with something else he never had, a hands-on coach with the ability to provide mentorship.
"I had never had a long-snapping coach, in terms of someone on the team who had experience working with long snappers before," McDermott said. "He was able to teach me things that I had never known before."
As a 23-year-old rookie, McDermott joins a special teams battery loaded with experience. Kicker
Jennings, a Pro Bowler in 2004 and ‘12, also had an impact on the former UCLA Bruin, teaching him how to kick in the unpredictable elements at Candlestick Park.
"It's a place that gets windy at times and it can effect your snap," McDermott said. "Especially for kickers, it changes the way they approach their game. He has played there for his career and it was great to pick his brain about how to get used to the environment you're playing in and just learning about what it takes to be a NFL long snapper."

As Jennings graciously departed from the place he called home for his entire career, McDermott made sure to thank him for his mentorship.
"Brian Jennings is an unbelievable long snapper and he was a great mentor to me when I first came here,” McDermott said. “I wish him the best as he goes on in his career."
