Pick 32 closes round one in the modern era; pre-1994 round 1 ended anywhere from #26 to #30. Either way, after the round-1 boundary the chart gets sparser at the top of every column except the trenches: OL and DL stay dense for a couple more rounds in any era.
How rare was this draftigami?
Trained on every pick through 1974, the model gave a center at #32 a 2.2% chance in 1975.
Center at #32, year by year
Each year's estimate uses only that year's draft and the years before it — no peeking ahead. The line smooths across neighboring picks and seasons so a single oddball draft doesn't dominate. The shaded band is the model's 90% uncertainty range.
