"In reality, I got kind of lucky because the guy kind of tripped. But it looked great," Juszczyk said laughing about the play, clearly not arguing with the outcome or the subsequent attention it earned him.

He still faced an uphill battle, though, even after a strong week at the Senior Bowl. A 6-foot-1 tight end had no chance at making an NFL roster. A 6-foot-1 fullback's odds weren't much better. Fullbacks were already becoming a niche in 2013. That's part of the reason why he was snubbed an invite to the NFL Scouting Combine. But Juszczyk kept the proper mindset, and his confidence never wavered. He didn't need all 32 teams to fall in love with him. All he needed was one.

"I figured I'd be able to find my spot somewhere," Juszczyk said. "My goal was that once I got my foot in the door, at some point I'd be able to showcase my receiving skills."

His transition to fullback mirrored his move to full-time tight end in college. Juszczyk was accustomed to the "fun stuff" in high school – being the star player, constantly having the football in his hands and making regular visits to the end zone.

Harvard head coach Tim Murphy provided him with a bit of a wake-up call upon his arrival in Boston.

"You can't play unless you block," Murphy told Juszczyk. "You need to become a better blocker, otherwise I'm not going to leave you in for the pass plays."

Juszczyk wasn't thrilled about that reality, but he embraced it all the same in order to get to the carrot that dangled in front of him. The NFL posed a similar challenge. The Baltimore Ravens wouldn't have used a fourth-round pick on him if they weren't intrigued by his proficiencies as a pass catcher. But those abilities were immaterial if Juszczyk couldn't excel in the grunt work mandated of a fullback.

"I wasn't going to make the team if I couldn't block," he said. "Once you're able to block, then you're on the field more. And when you're on the field more, then you get more opportunities to catch passes."
