Staff salaries are hard to get details on. What we do know is that the $300k number is just a little more than RJ was given ($288k), so it is probably not over the top money, but not a pittance either.
For reference, here is a link to all the Tournament coaches' salaries (http://sports.usatoday.com/ncaa/sala...ketball/coach/). I would note that the number reported for Vall is $350k plus bonuses, which is about 50 of 64 on this list, and about the same as UNC-Wilmington and Stephen F. Austin.
As for assistants, take a look at this GlassDoor data. Interesting to see some of the averages in the list itself (the aggregate is worthless, IMO). http://www.glassdoor.com/Salaries/assistant-basketball-coach-salary-SRCH_KO0,26.htm
Oregon Women's Basketball Assistant: $110,000 (ave of 2) = total of 2 would be $220,000. That is Pac 12 Women, mind you.
Northwestern Men's Basketball Assistant: $89,661 (ave of 5) = total of 5 would be $448,305. And that is a low end number in the Big 10 I am sure.
My take? I don't think $300k is a huge investment, as far as the industry goes. For Milwaukee, it is an increase, but probably not much more than the old staff would have been paid if they had been retained, after annual increases.
Looks to me like we just rolled over the old budget into the new coach and really haven't increased spend here at all....well, except for the money going to the buyout, of course, which does nothing for the program. Vall is making a bit less than RJ was, but not much, and the staff spend is a wash.
Another "sideways" move, I guess.
