I too think this is a bunch of crap, but she isn't just a "coach", she is also an instructor, so part of her pay, and I don't want to speculate what percentage, comes from teaching...Some of the other coaches do only that, coach...
The football and basketball coaches should be paid more...They bring in the revenue...Football at Emporia brings in the most athletic revenue, followed probably by women's basketball (the women's program is huge in Emporia and has been very successful over the last 5-10 years), then the men's program (probably, though, the men and women are even)...It wouldn't surprise me if baseball is next, followed by the volleyball and softball programs...
If she is the 5th highest-paid coach there and her program is 5th highest in bringing in revenue, then she's probably getting paid what she should be...
