ESPN analyst Todd McShay’s latest mock draft is sure to generate a lot of discussion among Pittsburgh Steelers fans.

McShay has the Steelers taking Oregon defensive end Arik Armstead No. 22 overall even though cornerback and outside linebacker are easily their biggest needs.

McShay has the Steelers picking Armstead in the first round even though outside linebacker Bud Dupree and cornerbacks Kevin Johnson, Marcus Peters and Jalen Collins are available at No. 22 overall in McShay’s fourth mock draft.

McShay writes that Armstead -- his seventh-best overall player in the draft -- is too good of a prospect for the Steelers to pass on with their first pick.

General manager Kevin Colbert has always been adamant that the Steelers draft for “want” instead of need. That is his way of saying the Steelers aren’t going to draft a player simply because it helps plug a hole on the team.

What is interesting about McShay’s pick, which at a position where the Steelers already have Cameron Heyward and the rising Stephon Tuitt, is Colbert and coach Mike Tomlin made it clear at the NFL owners meetings that they will add reinforcements at cornerback and outside linebacker through the draft.

They can probably wait until the second round to draft a pass rusher given the depth of those players but it is hard to see them passing on a cornerback if one they really like is available at No. 22 overall.

Michigan State cornerback Trae Waynes is probably not going to fall to the Steelers in the first round. And they don’t have the ammunition (i.e. extra draft picks) to move up to get him.

But if the Steelers have their pick of any other cornerback, as is the case with McShay’s latest mock draft, I see them using a first-round selection on the position for the first time since 1997.
