Steelers mailbag II: Who will start at left outside linebacker next season?

Here is the second half of the Steelers' mailbag. If you have a question, please tweet @ScottBrown_ESPN with the #mail.

@ScottBrown_ESPN: To be determined. I think the Steelers will sign an outside linebacker in free agency who can start in Jason Worilds ' spot. They could also re-sign Arthur Moats and have him compete for the starting job at left outside linebacker with a player on whom I assume the Steelers will use a high draft pick. But I think the Steelers - and their fans - will feel a lot better if they sign an outside free agent to come in and start.

@ScottBrown_ESPN: Landon Collins is the only safety worthy of a first-round pick. If the Alabama prospect is gone before the 22nd overall pick, it doesn't make sense to address that position until later in the draft. If all things are equal, I agree that the Steelers should take an outside linebacker ahead of a cornerback. But if the Steelers sign an outside linebacker in free agency, I think cornerback becomes the Steelers' top priority in the draft. And if there is a corner they really like at No. 22 overall, it is time to finally use a first-round pick on one.

@ScottBrown_ESPN: I can't see Bush signing with a team that has an every-down back who is as dynamic as Le'Veon Bell. There just won't be enough opportunities for Bush after Bell returns from an expected two-game suspension at the beginning of the season. And the Steelers will be wary of bringing in a proven back for what will be a bit role after what happened with LeGarrette Blount last season. Williams might be more agreeable than Bush to playing limited snaps. He isn't getting younger - Williams turns 32 in April - and the ninth-year veteran might accept a role as strictly a backup if he thinks he has a chance to win a ring. Williams also has a tie to the Steelers as he and quarterbacks coach Randy Fichtner were at Memphis together when the latter was the offensive coordinator, there so there is that.

@ScottBrown_ESPN: No, no, no and no. The Steelers don't need pass rushers that bad to take a chance on a player with as much baggage as Hardy. There were questions about him off the field even before he was charged with domestic assault. The allegations against Hardy painted a very disturbing picture. I can't see the Steelers -- or a lot of other teams -- wanting anything to do with him.

@ScottBrown_ESPN: I don't think the Steelers will re-sign Ike Taylor, who is the only free agent among the four. I think there is a very good chance that Troy Polamalu is released, as sacrilegious as that sounds. Polamalu is apparently intent on playing in 2015 but he will have to accept a reduction of his $6 million base salary in 2015 for there to be a chance of him returning to the Steelers -- with an emphasis on chance. James Harrison is an interesting case because if the Steelers don't sign an outside linebacker in free agency and Jason Worilds signs elsewhere, as expected, they will be both thin and inexperienced at the position. But I could see Harrison joining Dick LeBeau in Tennessee, especially if the Steelers wait on trying to re-sign Harrison. Brett Keisel, to me, is the most likely of the four to play for the Steelers next season. The 13th-year veteran showed last season that he can still play and he accepted a situational role in 2014. Bring Keisel back to provide depth and leadership for one more season and release Cam Thomas, who also has one year left on his contract.

@ScottBrown_ESPN: Quinten Rollins comes to mind in the second round after he did not test very well at the NFL scouting combine. Rollins is a project after playing just one season at Miami (Ohio), but he is intriguing because of his production in2014 - he intercepted seven passes - and upside. Oregon's Ifo Ekpre-Olomu is another cornerback who could drop into the late part of the second round after tearing his ACL in December. Like Rollins, the team that drafts Ekpre-Olomu may have to wait a little longer for a return on that pick, but he, too, is oozing with potential. One cornerback to keep an eye on in the third round is Oregon State's Steven Nelson. The 5-10, 197-pound Nelson doesn't have great size, but he ran the 40-yard dash in 4.49 seconds at the combine and broke up 24 passes in his final two seasons at Oregon State.

@ScottBrown_ESPN: My guess is that there have been talks between the two sides. Whether serious negotiations have taken place yet, I'm not sure. The Steelers do want Moats back and he would be ideal as a No. 3 outside linebacker who can start and also play special teams. Moats really seems to like playing for the Steelers, so the question the fifth-year veteran has to answer is whether he wants to seek more money and an opportunity to start elsewhere. I do think Moats and the Steelers are a good fit and I expect him to re-sign with the team.
