No matter how great you were in college, the transition to the NFL is fierce and difficult. If you're a quarterback, the pressure you're facing (literally and figuratively) is at least twice as fast and ferocious. If you're a running back, the gaps open and close with a quickness you may not have seen. If you're a receiver, you'll face defenders who are in more coverages and play them more expertly than you're used to. If you're an offensive lineman, you'll see stunts and games you didn't see with your prior team.

Oh, yeah…and in the NFL, defensive linemen know how to use their hands.

If you're a defensive lineman, you'll have to learn techniques you probably weren't taught in college just to survive. Linebackers and defensive backs will have to deal with playbooks that are much more complex than the ones they've used before.

It's a wonder there aren't more first-year busts. Those players who transcend the transitional difficulties are those who put in the work, develop accordingly and are in the right systems for their talent. Of course, it doesn't always work, and there are those who need time to adjust.

Just ask Los Angeles Rams quarterback Jared Goff about that. A year ago, he looked like one of the worst quarterback picks in NFL history. With a new offensive line, better receivers and a vastly improved game plan, he's playing at borderline Pro Bowl level.

This season, as in every season, there are those rookies who are struggling to adjust to the NFL for a host of reasons. Our NFL1000 team of scouts has been watching their game tape all the way through:

Lead Scout: Doug Farrar

Quarterbacks: Mark Schofield

Running backs/Fullbacks: Mark Bullock

Receivers/Tight Ends: Marcus Mosher

Offensive Line: Ethan Young

Defensive Line: Justis Mosqueda

Linebackers: Derrik Klassen

Secondary: Ian Wharton

Here are our suggestions for those rookies who are most obviously dealing with NFL adjustment issues.
