Uhm, who hired Rolston as HC? The owners were certainly supportive at the time.
As for Whaley, who knows? It's my conjecture, but I'm guessing that Pegulas aren't thrilled at how the last two weeks have played out and it wouldn't shock me that they're having second thoughts about their GM.
The rumors about TT benching are certainly troubling. As I said before, there's a world of difference in the "business decision" if it was to 1) avoid injury to TT, 2) evaluate EJ as a backup or 3) evaluate EJ as a starter. If Whaley was pushing for #3 among with other things that have made the franchise look inept, then you bet they're having second thoughts about him.
