In actual dollars, here's what I figured on the first page of this thread:
Pay an extra $476,430 and incur an additional penalty of 75% of that amount ($357,322.50). - as of now, we're a bit more than $430,000 over, which would incur a penalty of $322,500. Of course this is all fluid right now until the Top 10 are signed and we don't know what amounts over $125K to sign players drafted after the 10th round. But presently, we're only in the financial penalty level.
