While the Pats are hardly the standard, for anything but cheating, we’ll use them as the comparison. This was just from a quick 3-5 minutes of internet research so pardon of any errors…
The past 10 drafts
The Pats selected OL with picks: 23,29, 78, 85, 101, 105, 111, 118, 131, 140, 166, 179, 182, 195, 197, 210, 211, 221, 230, 245 (20 total picked)
The Steelers: 87, 92, 123, 128, 131, 173, 213, 219 (8 total picked)
They have definitely invested more heavily in the OL than us by a fairly wide margin.
