With the 117th pick in the 2015 NFL Draft, the San Francisco 49ers selected Oklahoma tight end Blake Bell.

Listed at 6-foot-6, 252 pounds, Bell played three years for the Sooners as a quarterback before switching to tight end during spring practices in 2014. 

"I'm feeling really comfortable. It's becoming a lot easier, it's just repetition," Bell said on Saturday after being selected in the fourth round. "It was my decision and ever since I made the switch, I haven't looked back."

Bell's reaction to being drafted by the 49ers?

"I got that call today and it was unreal," Bell said. "I'm just glad they gave me an opportunity, and I'm pumped."

As a goal-line package quarterback early in his college career, Bell tied for the team lead in rushing touchdowns with 11 in 2012. Oklahoma fans loved his hard-nosed running style so much that they nicknamed him the "Belldozer."

Last year, in his only season as a tight end, Bell caught 16 passes for 214 yards and four touchdowns.

Bell comes from an NFL family. His dad, Mark, played seven years in the NFL for the Seattle Seahawks and Indianapolis Colts and his uncle, Mike, played 12 seasons for the Kansas City Chiefs.

Another NFL connection, Bell is friends with 49ers fullback Trey Millard, who was selected out of Oklahoma in the seventh round last year.

"Me and Trey are really close friends to this day," Bell said. "I'm excited to be reunited with him and go to work."

Below are scouting reports and Tweet reaction on Bell:

NFL.com: "Looks good on the hoof with a frame suited to add just a little more weight. Former quarterback with a feel for space when running routes against zone. Confident pass-catcher with ability to run through safeties and maximize each catch. Plays with competitive spirit and very coachable. Improved by leaps and bounds as a blocking tight end. Keeps hands inside and plays with wide base and ability to sustain in pass protection. Had reps in which he held his own against Baylor defensive end Shawn Oakman."

CBSSports: "Three-year starter at quarterback in college who is still very raw. But at 6-foot-6 and 252 pounds with long arms and big hands, he has the tools to develop into an all-around tight end."

Sports Illustrated: "Good size, moves well for his frame. Bruising, straight-forward runner ... nicknamed "Bell Dozer." Good hands for a player new to the position. Willing blocker and not afraid of contact. Ran well at the combine—second in 20-yard shuttle (4.32) at position. Unlike former QBs like Tim Tebow or Eric Crouch, Bell willing to give up the position to continue his football career—says he's all tight end now."
