It was only 5/6 years ago that ILB Devin White went 5th overall, Steelers panicked and moved up for Devin Bush because of the scenario you described with the clear hole left by Shazier.
I don’t believe that they “panicked” and moved up. I believe he was their guy all the way, and when White went off the board they did what they felt they needed to do to be sure to get their guy. You can make the argument that moving up to get the guy was a reach, and you would be right, as proven by how things worked out. It also could have worked out and they got their guy for years to come.
The Steelers have need at WR and DL and CB too, so if there were more OT/C's taken early, it would be more likely that they take the BPA, because that one spot, OC, does not make them a SB contender.
I agree that they ALSO have need at WR, DL & CB. I just happen to rate the need lower than C & RT.
WR - Pickens is WR1 right now, no matter if they pick a WR in the 1st.
DL - The line is functionally solid right now, but you don’t draft early for depth
CB - They are looking for CB2, who may already be on the roster, so again this is a depth pick early situation.
C - There is nobody current on the roster to fill this position that is better than Cole was, otherwise they would have replaced him last year.
RT -There are a couple young guys in the wings that may work out, but again, they were not better than the weak link manning the LT position, since they didn’t play them @ RT allowing Jones to play where he should be playing.
MY OPINION is:
3 are depth moves with a possibility of upgrade
1 is an upgrade possibility
1 is a Starting position need.
I value the picks in this order C, RT, WR/DL, CB, ILB, QB, CB, DL, WR, S
Center is the biggest need, but if things go as I hope, it can wait till round 2 if a RT is available @ 20 with all C’s still on the board. if it works out, they get 2 starters on the OL, and are set for a decade. We can argue about who that RT pick is, Mims, Barton, etc. Make no mistake though, I would take the C in round one if I need to, and not lose a minute of sleep.
