Eagles vs. Packers: Which players (and coaches) hurt their stock?

The Green Bay Packers' third preseason game is now in the books, and so we have our next batch of player evaluations. For the second time in as many weeks, the news is dominated by an injury to a major player, this time to star wideout Randall Cobb. While it does not appear as though the receiver will miss much time, we will henceforth keep this a Cobb-free zone.

Here are the players that hurt their stock the most during Saturday's game against the Philadelphia Eagles:

Ron Zook

Sure, he doesn't lace up cleats, but new Packers special teams coordinator Ron Zook has a target on his back after his units combusted on Saturday. In total, Green Bay incurred eight penalties on special teams, more than one of which resulted from an improper amount of players on the field. And it could have been worse. On Jeff Janis' fair catch during the third quarter, the Packers appeared to have only 10 men on the field, though the refs didn't see it.

Special teams can't and won't perform this poorly come the regular season. However, they require such improvement that it's already difficult to envision that phase of the game being anything other than a liability in 2015.

Sam Barrington and Jake Ryan

Usually, the stock up/down selections are made with an eye on those straddling the fringes of the roster. These are not those players. Both Sam Barrington and Jake Ryan fully expect to make the final cut. However, the Philadelphia Eagles exploited both in pass coverage over the weekend.

Barrington was burned twice for touchdowns, including an opening-drive catch and run by Darren Sproles. When the linebacker left the game with an injury, Jake Ryan found himself on the short end of another Sproles touchdown reception.

That Sproles managed to make linebackers look silly is nothing new; the diminutive but versatile tailback has frustrated NFL defenders for a decade. However, given that Barrington is a starter (and the team's preferred coverage linebacker in sub packages) and Ryan is a relatively high pick for an off-ball linebacker, the Packers can't be pleased.
