Three impressive rookies from Week 1

The preseason is always a great chance to get a first look at the rookie class, with the obvious caveat that 20 snaps in a preseason game does not a career make. Here’s a look at three who really impressed this weekend:

Frank Clark, DE, Seattle Seahawks

Off-field issues aside, Clark can play, and he showed up in all facets of Seattle's game versus Denver to produce a +6.9 grade overall. He defeated every type of block thrown at him in the running game to grade at +5.6, to go with a hit and two hurries. He even tracked down a screen from behind.

La’el Collins, G, Dallas Cowboys

We’ve all seen “the block” by now, as Collins drove a second-level linebacker from San Diego to the Dallas/Fort Worth area, but it was an impressive debut beyond just that one play. He did his best work in space, and while he wasn’t perfect in pass protection (two hurries), it was a nice start in his quest to help one of the league’s best offensive lines.

Quinten Rollins, CB, Green Bay Packers

Tied for the league lead in targets with 10, Rollins handled everything that was thrown at him against the Patriots. He finished at +3.0 in coverage, allowing five catches into his coverage for only 26 yards, defending two passes, and keeping plays in front of him for the most part.
