Illinois can spend. If Illinois offers to double Buzz Williams' salary, I don't see him saying no to stay with Marquette for these reasons:
Buzz Williams doesn't pretend to have 'integrity' like Shaka seems to call it.
The Big East is a little unstable with the loss of two of their top programs.
Some rumors Buzz Williams is not happy with some Marquette board members.
Marquette's profit margins are razor thin so I doubt they will be able to match Illinois' offer.
I really hope those 2 racist prikks on the trustee board who are insisting on a black head coach will rest now considering they threw a ton of money at a black head coach and he turned it down to stay in the god awful CAA (2 elite CAA teams lost to Mercer in the last few nights, embarrassing)
