No, Heath Miller is not hurt, but due to needing his blocking abilities on the offensive line lately, his 
effectiveness in the Steelers passing game has been hindered. It’s pretty simple really, if you take one target away from a quarterback, you limit your offense; at least to some degree.
Heath Miller, and rookie David Paulson, have spent significant time helping out Mike Adams on the right side of the Steelers offensive line. You can hardly blame Toddy Haley and Sean Kugler though; having a rookie playing OT in the NFL is never easy.
They’ve tried to limit the impact of those growing pains by putting Miller or Paulson alongside Adams. Consequently you’ve taken away a potential target for Charlie Batch, Byron Leftwich, Ben Roethlisberger, or whoever continues to take snaps in Pittsburgh.
Through the first 7 weeks of the 2012 season, Heath Miller had 6 Touchdowns and 35 of his 45 receptions this season. The last 3 weeks Miller has no TD’s and 10 catches.
Enter Plaxico Burress. Teams can no longer feel confident that the Steelers don’t have a tall redzone threat. Plax is 6’5 as is Miller, and is more than capable of going up for a jump ball against any DB in the league.
Burress may not be the guy he was even 5 years ago, but he’s still capable of being effective in his role; which is likely to be in the redzone, sideline passes, and any jump ball opportunity.
As long as the Steelers need to keep TE help over on the right side, they now at least have another option to help equalize that loss.
