We all know great players don't always make great coaches. Dawn Staley has of course been phenomenal but I think it helped she was at Temple for a few years, which frankly had less of a spotlight placed on her despite being a Philly native. Whalen grew up in MN, played at the school, won titles with the Lynx, and was a newbie entering a job in a major conference so the spotlight and expectations on her were large. I suspect Dawn learned some things in her time at Temple, plus it appears she's surrounded herself with good people both there and SC.
Tina Thompson did very poorly at UVA, NMP didn't do very well at MSU, Rizzoti struggled at GW after being moderately successful at Hartford, Stephanie White was terrible at Vandy, and there are of course plenty of others. Whalen won't be the last coach at all who gets hired on name only to underperform.
