They will need to go 35-38 the rest of the way to have 90 losses.
Seeing as how they are probably going to be 10+ out approaching the deadline, I would assume they will be trading away players. 90 losses should be a lock.
25-48 would then get them to 100 losses, which seems hard to believe even if they do trade away some players. I don't think we will see 100 losses. Unless of course they go full blown sell off and trade guys like Cease or Robert, but I don't see it.
