Wow, a ton of great questions. The second part of the mailbag will run Monday morning and my apologies to those who sent a question about the Steelers trading for New Orleans Saints cornerback Keenan Lewis. I got four or five of them and give my thoughts with the first question of the mailbag. If you have a question, please send to @ScottBrown_ESPN with the #mail.@ScottBrown_ESPN: My ESPN colleague Mike Triplett, who covers the Saints, reported that Lewis wants New Orleans to guarantee the rest of his contract. He is due base salaries of $5 million and $5.5 million in the final two years of the deal, and I can't see the Steelers guaranteeing those if they have interest in Lewis. If Lewis is willing to give up his demands, then re-acquiring him is something the Steelers should look into. But right now I think it is a long shot, at best, of him returning to Pittsburgh.
@ScottBrown_ESPN: The Steelers found their backup to Le'Veon Bell when they signed DeAngelo Williams to a two-year contract. I think they could still draft a running back, even with youngsters Dri Archer and Josh Harris also on the roster. It is a deep draft for running backs and they always seem to slip in the draft, so the value might be too great to pass on one in the fifth or sixth round. Landon Collins would be a logical long-term replacement for Troy Polamalu if the Steelers are not sold on Shamarko Thomas. If he is available at No. 22 overall, Collins will tempt the Steelers. But if they have a cornerback or outside linebacker close to or on par with Collins as far as a draft grade, I think they address one of those positions in the first round.
@ScottBrown_ESPN: I don't think there will be any seismic shifts as far as how the Steelers play defense. Keith Butler is a 3-4 guy who spent more than a decade learning under Dick LeBeau. I'm sure he will make some changes and put his own imprint on the defense. The biggest change, as I have written before, is that Butler now has more of a say in the draft. He used to give his opinions on linebackers. Now he will offer his input on any defensive player the Steelers consider drafting.
@ScottBrown_ESPN: I get the sense that they are very happy with the improvement he made in 2014 after playing sparingly as a rookie. And Markus Wheaton is only going to get better, given his work ethic and the confidence he gained after catching 53 passes for 644 yards and two touchdowns last season. I think Wheaton and Martavis Bryant will be interchangeable as No. 2 and No. 3 wide receivers next season, depending on the package the Steelers use. The Steelers have to feel very good about their top three wide receivers with those two and Antonio Brown. They need some depth at the position, but it is another strong draft for wide receivers and the Steelers will sign a wide receiver in free agency or re-sign Darrius Heyward-Bey.
@ScottBrown_ESPN: Jordan Cameron received a nice pay-day from the Miami Dolphins, though I'm a little surprised the $15 million deal wasn't for longer than two years. That is probably the Dolphins protecting themselves if Cameron has concussion issues in Miami. If he stays healthy, Cameron can hit the open market in two years while he is still in his 20s or sign a long-term deal with the Dolphins. I doubt the Steelers were involved with Cameron, given the money it would have taken to sign him. No word on Nate Washington, though I agree with you that it would make a lot of sense for the Steelers to bring him back to Pittsburgh as a No. 4 wide receiver if he agrees to a reduced role and his asking price isn't too high.
@ScottBrown_ESPN: He has certainly made the offseason interesting, and Eagles beat writers have probably lost part of their minds trying to keep up with all of the news coming out of Philadelphia. It is obviously too early to tell whether Kelly's roster makeover will be a success, but I will give him this: if he goes down in Philly, he will do so on his terms.
@ScottBrown_ESPN: The Steelers got their free agent - and a proven backup to Bell - when they signed Williams on Friday. I still think there is a good chance they also draft a running back. Consider that since Mike Tomlin took over as head coach in 2007, the Steelers have taken a running back in seven of eight drafts. The lone exception is 2007. That recent history and a draft that is strong at running back is why it wouldn't be a surprise if the Steelers addressed the position again this year. I wouldn't expect them to take one, however, before the fifth round, given their needs on defense.
@ScottBrown_ESPN Will they seek a back-up RB in f.a. or the draft?— Matty Icebucket (@pittsburghfan76) March 12, 2015
@ScottBrown_ESPN: He is scheduled to visit the Steelers on Monday, so that is a good sign if the team really wants to make a play for the fifth-year veteran. There aren't a lot of cornerbacks left on the open market, so it could be Robinson or bust unless the Steelers go bargain-shopping, as they did last year when they signed Brice McCain to a one-year, $795,000 contract.
@ScottBrown_ESPN Is Patrick Robinson a real possibility? We're mighty thin on CBs with Mccain gone.— Shai Landesman (@ShaiLandy) March 12, 2015
