Nitpick - Pasta didn’t fall. He went 25, which is right around where analysts had him:

McKenzie had him at 22, Button 25, THN 23, ISS 33. In retrospect he should have gone too 3 that year, probably 2nd (Drai, Pasta, Point), but at the time ~25th was pretty dead-on pre-draft expectations.
I do agree that Kent Johnson could fall, though. He’s highly skilled, but there are legit questions about his compete level, these types of players are riskier picks, with potential to fall if teams play it more conservative.
