So I took AgentDib's chart and added the original draft position of free agents and trades, because I don't feel that the distinction of being obtained from another team is all that absolute and I wanted to see if the numbers would bear that out.
I then took the liberty of regarding picks from #32-40 as first-round picks for two reasons: 1) a lot of us are aware that there isn't that much difference in talent from pick #15 to pick #40; 2) #40 seemed a good cutoff because, at least right now, there's a desert in picks from #40-50 on NFL offensive lines.
Here were the results.
It did a fair amount more for the top half than the bottom half. In light of that, in addition to OL being a strength of this draft, I might be up for going OL in round 1 this year for sure, unless a defensive front seven stud falls to us.
But what this chart tells me more than anything is that being tops in offensive line quality doesn't guarantee you run the table. The top 7 OL's include the Colts, Falcons, 49ers, and Jets, none of whom made it. On the other hand, seven playoff teams (including 4 division winners) range from #14-#24. I'm willing to bet that would go against most people's expectations, but it matches the trend over the last 15-20 years that the offensive line is actually declining as a predictor of a team's quality.
I tend to think it'll be an OL pick because of the draft's strength and the need to protect a 35-year-old QB we'll be stuck with. But if we take someone else who's good and he's not an OL, I won't lose sleep.
