Steelers sign G/C Stefen Wisniewski (2 year, $2.85 million): B+ Grade
The Steelers lost a couple of offensive linemen this offseason, thanks to Ramon Foster's retirement and B.J. Finney's departure to Seattle, so they had to add at least one blocker in free agency. Stefen Wisniewski may not be a flashy name, but he's a solid addition.

Wisniewski started every playoff game of Kansas City's Super Bowl run. He's a terrific backup because he's a quality blocker who can be stationed at every position in the interior. He was signed for very little, so it's hard not to like this addition.

Steelers sign TE Eric Ebron (2 years, $12 million): B Grade
It's difficult to believe that Eric Ebron is just 27 years old because it seems like he's been in the NFL forever. He still has loads of potential because he's so physically gifted. The Steelers will be hoping that he can finally live up to his upside.

I have a feeling that's not going to happen. Ebron is incredibly frustrating, whether it's because he drops too many passes, runs bad routes or quits on his team. However, the Steelers aren't taking much of a risk with these terms, so I'm OK with this move.
