To get to 90 wins, they'd need to go 61-36 the rest of the way., which is .628 ball. Just don't see that happening.
.A .600 pace gets you to 87 wins, probably not enough. Since the end of the 12-game losing streak, they've gone 22-20, a .524 pace. Keep that up and you're looking at roughly an 80-82 record.
