4. Foley Fatukasi, DT, NY Jets - 6th round, 180th overall (2018)
A sixth-round pick in the 2018 NFL Draft, Foley Fatukasi appeared in just one game as a rookie and entered the 2019 season firmly on the roster bubble. It didn't take long for him to develop into a key defensive contributor that season, however.
Fatukasi played a career-high 40 percent of the Jets' defensive snaps in 2019, establishing himself as arguably the team's best run defender. His role would only increase from there, playing 47 percent and 53 percent of snaps in the two subsequent seasons.
The only interior defensive lineman in the NFL to finish with a higher Pro Football Focus run defense grade between 2019 and 2020 was Aaron Donald. Fatukasi was genuinely one of the best run defenders in the NFL during his time with the Jets.
After two seasons in Jacksonville, Fatukasi found a new home with the Texans this offseason amidst rumors he could return to New York. His development from a nondescript sixth-round pick into a rock-solid defensive standout makes him an obvious candidate for this list.

3. Quincy Enunwa, WR, NY Jets - 6th round, 209th overall (2014)
The oldest player on this list, Quincy Enunwa earns a slight nod over Fatukasi due in part to the fact that he was drafted 29 picks later, albeit still in the sixth round.
Enunwa's story will always be a tale of what could've been. The only successful member of the infamous John Idzik 12-player class of 2014, Enunwa developed into an important part of the Jets' offense.
He finished as the team's leading receiver in 2016, hauling in 58 catches for a team-best 857 yards and four touchdowns. Unfortunately, injuries derailed his career from that point, and he'd appear in just one game after signing a four-year, $36 million extension.
Enunwa's Jets career could have been even more memorable had he stayed healthy, but even with the injuries, he still accomplished quite a bit for a sixth-round pick.
