The overall endowment is always a good measure for a universities ability to raise money. The ACC's privates schools have the following endowments:

Miami - 1.05 B
WF - 1.35 B
Syracuse - 1.39 B
BC - 2.58 B

You probably did not not know how "poor" Miami really is in the scheme of things.

Pitt has 4.17 B (No, the fig leaf of "State Related" is bull ****, Pitt is private as is their Board)
ND has 12.0 B
Duke has 12.7 B

If you look at the private schools with the smallest endowments and then look at their enrollment you get:

WF 5.3K and 3.3 K Grad 8.6K Total
BC 9.3K and 4.3 K Grad 13.6K Total
Miami 11K and 6K Grad 17K Total
Syracuse 14K and 6.8K Grad 20.8K Total

It's easy to identify WF as the smallest private with the largest challenges, but choosing between Miami and BC is difficult. Syracuse is either the largest of the small privates or the smallest of the large privates.
