Ealing you are probably totally correct in your potted History of Spurs. Struggling to think of all the successes at Bournemouth, Portsmouth, Southampton and Rangers in developing players.
From Wiki:
Bournemouth -
In his first season at the helm, Redknapp helped Bournemouth avoid relegation to the Fourth Division. Bournemouth also caused a shock in the FA Cup when they beat holders Manchester United 2–0 in the third round. Bournemouth won the Third Division title in 1987 with 97 points; this broke the club's record for the most points scored in a season
WHU -
West Ham finished eighth in 1998, and took fifth in 1999, which saw them qualify for the Intertoto Cup, in what was their second-best ever season in the top division. In the 1999–2000 season West Ham won the Intertoto Cup and qualified for the UEFA Cup;
Pompey (1) -
However, after the club's poor form he replaced manager Graham Rix in March 2002. Redknapp managed the club to the Division One title in the 2002–03 season, gaining promotion to the Premier League, replacing his former club West Ham.;
Soton -
Car Crash, Big Mistake (Doesn't actually say that in Wiki, but it should. Anyhow, wasn't there long enough to develop anything, esp with Sir Clive W interfering);
Pompey (2) -
Redknapp returned to Portsmouth on 7 December 2005 with the club threatened by relegation to the Championship, although not in the relegation zone. At first it looked like Redknapp would be heading for a second successive relegation, but a fine run of form at the end of the season... ... ensured Portsmouth's survival. In the following season, Redknapp led Portsmouth to a ninth-placed finish which was the club's highest league finish since the 1950s.... ... He guided the club to their first FA Cup Final in 69 years, where they beat Cardiff City, on 17 May 2008, to win The FA Cup 1–0... ... He is the last English manager to win a major English trophy;
Spurs - See earlier post;
QPR -
Car Crash, Big Mistake (though tbh, they're pretty much unmanageable, as a succession of managers have proven)
I am afraid you have not convinced me and still believe that he is not the genius the media ( and you) would have us believe !!!
The problem with Harry is that he polarises people. There are those who (often inspired by Harry's pals in the media) who believe he can do no wrong.
And there are others (often inspired by those who have had financial dealings with him) who believe he can do no right.
Me? I certainly don't believe he's a "genius", but neither do I believe that he's rubbish, either. Instead I reckon that at the right club, with the right Chairman (esp), then he can be a very good manager indeed. However, he has frequently chosen the wrong club, often for the wrong reasons, leading to a very patchy record.
All of which is why I actually think he would have made* a good England manager, since there would be no money/transfers involved, far less opportunity to get up to no good (hence fewer distractions) and he'd have had to work with the players given to him (Peter Crouch and Jermain Defoe a hundred caps each!).
* - Past tense, because he's, er, past it now, I expect.
