Some pretty big assumptions in the OP, OP.
Like, CJP has offered the job to a lot of people.
Like, a lot of people have turned the job down.
What if, maybe, just maybe, Pruitt knew exactly who he wanted before Helton ever left, and Pruitt quietly asked that person, and that person agreed (but only after that person's current team's season is over), and it has all been settled all this time except for a delayed announcement and a mouth-breathing fan base?
I consider that scenario just as likely as any other offered on these boards over the past month.
