If Rod Smith isn't in a coma, start him. He's a proven top-notch receiver. Starting out with a home game, even vs the Rams, never hurts a guy's chances to perform.
Galloway goes up against Houston in his first game. HINT HINT!
The choice becomes: Glenn or Burress?
Glenn is one of the most talented WRs in the game, playing in one of the highest powered offenses. The potential drawback here is that he's new to Green Bay and basically didn't play last year.
Burress is a big, sure target who will just about guarantee you some numbers. The downside here is that he hasn't put up big WR numbers yet ... and maybe he never will. The Steelers would rather run you over with a Bus

than try to outgun you.
My advice: Start Glenn. He has the most potential of the two, and he's facing Atlanta, who was almost dead last vs. the pass last year. Burress, on the other hand, will be in an AFC championship rematch grind against New England. Only 3 teams allowed fewer passing TDs last year than the Pats, who have a bend-but-not-break secondary. Glenn can score a couple receiving TDs by himself. Pittsburgh will be lucky to get one for the whole game. The road team in this kind of matchup will be VERY conservative. Also, Ward's injury may allow the Pats to focus on Burress. While that may provide opportunites for other receivers, two Patriot DBs on Burress spells lights out.
