I think you meant "I think McDaniels will not take another job" right? The double-negative use here is confusing.
I personally hope he doesn't go, partially because I do think he does a good job overall, and also because I don't really want to have Mac having to learn under a new OC in his second year. Building continuity under McDaniels in Year 2 feels really important.
Regarding staying in New England - yeah, it's rumored he's paid extremely well for an OC (like, HC-level dough) so he'd have to both be paid a huge sum and also be offered a golden opportunity to leave. The Vikings are not a golden opportunity. And even if they were, he might not, because Bill only has a few years left at most and Josh isn't old (he's only 45) so he can certainly afford to wait a few years if he feels it's very likely Kraft will tap him as next in line.
