Pittsburgh Steelers need more from rookie draft class vs. Packers

The Pittsburgh Steelers continue preseason play at 1 p.m. ET Sunday vs. the Green Bay Packers at Heinz Field. Here are a couple of things to watch for during the game:

Why watch: The Steelers need more from their rookie class. First-round outside linebacker Bud Dupree hasn’t flashed much in two preseason games. Third-round receiver Sammie Coates has had an uneven camp, though he did catch five passes against Jacksonville. Fourth-round corner Doran Grant hasn’t seen much game action despite showing good instincts in practices, and fifth-round tight Jesse James had two critical drops in his preseason debut against Minnesota. Luckily for the Steelers, their veteran depth assuages the need for these rookies to produce right away. But the team could use a reminder that the future is in good hands. ... The Steelers’ defense missed some tackles and gave Blake Bortles too many open passing lanes last week. Hey, it’s the preseason. Now it’s Week 3, so expect the Steelers to mix and match looks for better results. Watch the safety position -- starters Mike Mitchell and Shamarko Thomas have missed time due to injuries and need to find a rhythm together on the field.

Did you know: The Steelers have switched the positions of at least three players mid-camp. Left tackle Alejandro Villanueva moved to right tackle this week. Former Canadian Football League standout Ian Wild moved from safety to inside linebacker. Quarterback Tyler Murphy is a wide receiver this week. This is a good thing -- it means the team likes the players enough to experiment with them. All three should see valuable snaps against the Packers.
