NFL fans know all about the big-time rookies through two weeks. Weapons such as Jaylen Waddle and Ja'Marr Chase have made highlights, and defenders like top-10 pick Patrick Surtain II have had immediate impacts. 

But what about those who didn't carry as much hype?

Many rookies drafted outside the first round, or who simply didn't enter the league with household-name status, have made splashes just as big, if not bigger than the recognizable names. It could be an unheralded player in the trenches or a middle-rounder playing an unexpected role. 

These are the most unheralded rookies already making a big impact. 

 

Josh Myers, C, Green Bay Packers

One could argue Josh Myers has been the NFL's best rookie offensive lineman. 

He's no Penei Sewell in the name-recognition department, but Myers, a second-round pick by the Green Bay Packers, has played in 100 percent of his team's snaps, earning a 74.1 Pro Football Focus grade, putting him in the "starter" range. For comparison, Sewell, the No. 7 selection, has a 71.0 mark. 

Myers, 23, has been an anchor in front of quarterback Aaron Rodgers, as he's yet to allow a sack or get flagged and has excelled in pass blocking.

And the important additional layer? Green Bay let star center Corey Linsley walk during the offseason, so finding a player of the Ohio State product's caliber is a boon.

 

Asante Samuel Jr., DB, Los Angeles Chargers

Considering he hails from Florida State and has a former All-Pro for a father, Asante Samuel Jr. has more name recognition than most non-first-round rookies, but it was still hard to envision him standing out much on a defense that features Joey Bosa, Chris Harris Jr. and Derwin James. 

The 21-year-old has done just that, though, as the Chargers have thrown the draft's 47th pick out there on 92 percent of the defense's snaps. He's responded with a 70.5 PFF grade (in the starter range) and has already picked off a pass on 10 targets. 

Samuel is allowing a 40.2 passer rating when targeted, according to PFF, which puts him among the NFL's best. 

At this rate, offenses might stop trying to pick on the rookie.
