I would say 40 - 49% of the Bills fan base probably wants Whaley fired right now. If Bills do a typical dog chasing tail show next season and the offense digresses substantially and TT is not here, look for Whaley's head to roll sooner rather than later. Especially with another losing record.
There are numerous factors obviously. How does TT perform elsewhere? How does our QB perform? But I would say Whaley is on somewhat thin ice but still firm standing.
Of course i could see a worst case scenario for Whaley: TT succeeds elsewhere, our answer at QB flops, and the team has another losing season. If all of those factor come together at once next season, i cant see Whaley surviving that.
