From Dale Lolley's blog, "NFL From The Sidelines"...

The Steelers signed veteran wideout Jerricho Cotchery on Thursday, adding some key depth to a position that has been banged up considerably at training camp.

It remains to be seen how Cotchery fits into the wide receiver depth chart, but the Steelers were concerned that they had precious little veteran depth behind Hines Ward.

Yes, Mike Wallace is an emerging star, but his inexperience showed up in the Super Bowl. And with Emmanuel Sanders and Antonio Brown entering just their second year – and Sanders missing the past two weeks of practice – the Steelers were concerned about what would happen if Ward were injured.

The move doesn't bode well for Limas Sweed and possibly Arnaz Battle.

Sweed is all but done in Pittsburgh now, while the signing of Cotchery shows the team has no use for Battle as anything but a special teams cover man.

It's a shame rookie Baron Batch suffered an apparent season-ending ACL tear Wednesday. But it opens the door for Jonathan Dwyer to make this team again.

It also assures Mewelde Moore of a roster spot.

Second-year pro Chris Scott missed all of training camp in 2010 with a broken foot, but the Steelers have been impressed enough with his play in camp this year to give him a legitimate shot at starting at right guard.

At 6-4, 319 pounds, Scott is nearly as big as 2010 starter Ramon Foster, but much more agile.
