Biggest recruitment busts of the cycle?

It's not a recruiting bust if the person is probably gonna flip the seat.  

Senate: The Texas Senate race

House: PA-1

TX and GA (both regular and special) for Senate Democrats, Kansas for Senate Republicans. For both parties, I think pretty much all of the other Senate races either a)have average-ish or better candidates (here I'm excluding incumbents, including McSally), or b)were never winnable to begin with.

Jon Osoff has actually been running a stronger campaign than expected.  It's not like he's a top-tier candidate or anything, but I don't think he can really be called a recruiting bust at this point.
