So you're basing your assertion that he'd "go now" purely on his previous affiliations with the club? Most managers are ex players, most of them have played for various teams (/have soft spots for them)- yet most don't let their career moves be solely guided by who their past employers were.
1) Harry will get paid more at QPR
2) He has a great relationship with the owners, which must make his job a lot easier. That can't be understated.
3) He'll get more funds at QPR
4) I get the impression he cares what people think of him. He cares about the "Redknapp legacy", and knows being relegated with QPR then not returning them to the PL, would be a blot on his copy book.
5) Him and his coaching staff are settled here.
6) West ham are second from bottom, and three points from safety.He's just been through one relegation blighted campaign, I don't think he'll fancy another. They've just been pasted 5-0 by forest, who only stuck 2 past us.
Etc etc.
I'm assuming if you're slinging statements around like "he'd go now" and "his heart has never been in it", you must've really done your research, and kept thoroughly up to date with all his public appearances re QPR. You'll be carefully analysing his body language/mannerisms in all his pre/post match interviews etc.
I'll probably have to defer to your expertise on that one.
Personally though, whilst watching his weekly interviews on QPR player I've noticed no indication that he's unhappy at the club. Media regularly quiz him on different links with managerial positions, what it's like at QPR, what the plans for the future are- and the responses are always satisfactory/honest.
The only Arry' evasiveness/spin there's been this season has related to transfers/opinions on matches; which is par for the course.
