I wonder what the fear is in pulling Cassel?
That it's an indirect admission of a mistake?
Pioli isn't above making a mistake.
Neither is any other GM.
Admit you were wrong about Cassel and move on.
Guess what? If his replacement plays well...you'll get credit for it.
That's the job.
It's like when I'm right I'm right, when I'm wrong I could been right, so I'm still right cause I coulda been wrong.
