Here's my shot at who I think should/will be active this Sunday when the Atlanta Falcons come to town. More past the jump:

QB (2): Dennis Dixon, Charlie Batch

RB (3): Rashard Mendenhall, Mewelde Moore, Isaac Redman

TE (3): Heath Miller, Matt Spaeth, D.J. Johnson

WR (5): Hines Ward, Mike Wallace, Antwaan Randle El, Antonio Brown, Arnaz Battle

OL (7): Max Starks, Chris Kemoeatu, Maurkice Pouncey, Trai Essex, Flozell Adams, Doug Legursky, Jonathan Scott

DL (6): Aaron Smith, Casey Hampton, Brett Keisel, Ziggy Hood, Chris Hoke, Nick Eason

OLB (3): James Harrison, LaMarr Woodley, Thaddeus Gibson

ILB (4): James Farrior, Lawrence Timmons, Larry Foote, Keyaron Fox

S (4): Troy Polamalu, Ryan Clark, Will Allen, Ryan Mundy

CB (5): Ike Taylor, Bryant McFadden, William Gay, Keenan Lewis, Anthony Madison

Specialists (3): Jeff Reed, Daniel Sepulveda, Greg Warren

Inactives (8): RB Jonathan Dwyer, G Ramon Foster, T Tony Hills, WR Emmanuel Sanders, LB Jason Worilds, LB Stevenson Sylvester, CB Crezdon Butler, QB Byron Leftwich

I feel fairly confident about this roster. Of note:

• Antonio Brown and Arnaz Battle make the game day roster based on their special teams prowess, leaving Sanders to ride the pine in favor of the experience and smarts of ARE, especially with a green QB starting.
• Thaddeus Gibson seems to have shown more in the pre-season, so he's active for ST work and perhaps the occasional passing down in relief of Woodley/Harrison.
• Sylvester is still green and therefore inactive, but look for him to make a push to displace Foote later in the season.
• Dwyer is pretty much getting a redshirt year, and I don't expect to see him active as long as the three main backs are healthy.

What do you think, people? What did I get right/wrong in your opinion? We'll get to find out soon! :)

UPDATE: edited 9/7 to replace Tony Hills with Jonathan Scott, as he's the backup LS
