Random fan here that never wrestled, but I may be able to provide a few insights. Purdue has had several good years in a row from 2019-last year, but they are very young this year, so while recently they have had a really solid lineup (7 or 8 NQs with several possible AAs that are voodoo hexed never to make it (Brunner, Lydy, Schroder, etc...) This year they are wrestling a LOT of younger guys.
No, they rarely lose to teams like Drexel, but they're young this year. Doesn't help that for reasons unknown to me, 197 blood round/possible AA Penola isn't wrestling this year, so they are going from 3/4 studs down to 2/3, with many weights currently looking like they aren't going to NQ.
Currently it seems like 125, 141, 157 are the only NQ locks, and Purdue may get one or two more in with good Big Tens, which is definitely down.
