Maybe more than 50%? It's just another statistic that makes him look very average to be honest. You want great? Look at Jenkins at Swansea? Lost a lot of managers but got every appointment right to not hinder their progress. You may say it's easier to achieve what they did rather than what we are trying to do (although it isn't really, they just made it so) but they could have easily slipped back into League 1 or mid table championship had they made a seriously bad hire.
Levy's made 3 good hires and 3 bad ones. Average, not great and not terrible. Certainly not 'all hail the unquestionable king Levy'. I actually think this next hire will be a good one. First time a manager is taking over a quality squad that is poised in the top 6, and doesn't have to be in a fire fighting situation.
You can't just say 3 good hires, 3 bad hires. That's with hindsight.
Hoddle was a good appointment at the time, as he was having success with Southampton, played good football and was a club legend, it was a way of attempting to appease the fans while ENIC got to work restructuring the club and improving revenue streams. Unfortunately, the squad at the time was poor and with ENIC not yet able to improve the revenue/income or make serious playing staff investments of their own due to buying the club, Hoddle had to make do with older players on free transfers or bargain basement signings. He did well for a while, but it appeared he lost the dressing room in his last season and the results took a big nose-dive so he had to go.
I'd say the only real bad hire was Santini as 2bf it looked pretty ropey straight away, but at least the 'structure' put in place around him with Arnesen and Jol meant it wasn't too damaging. Jol was chugging along nicely, but his record against the top clubs was pathetic and he'd started to slide in terms of performance (the second season of 5th place finish was not nearly as convincing or close to getting 4th as the first and from memory we kind of limped into 5th place rather than the previous season when we were 4th for most of the season and got knocked down into 5th due to lasagne gate on the last day).
So Ramos, who was probably the hottest property in Europe management wise becomes available, who'd blame Levy for taking the chance on upgrading?
Ramos then obviously had to go after the infamous 2 points from 4 games.
Redknapp was clearly the right appointment at the time to avoid relegation, and he probably was brought in as a fire-fighter. He did perform way beyond expectations in his second and subsequent seasons however, but clearly had working relationship issues with Levy and I think Levy always wanted to reintroduce the contintental DOF structure to bring greater stability and quality control to signings and squad development. Don't think Redknapp would have stood for this and with his off the field stuff becoming a distraction, whether it was court cases, interviews with the window down or his flirting with England, i think it was probably time to part.
Think AVB was the 2nd ropey appointment by Levy. He got done by his presentation and enthusiasm when i think there were better candidates at the time, more compatible with the clubs ethos.
However, at the end of the day, the ropey appointments haven't really prevented the upward trend in the club's performance and more importantly status. Players and managers now see us as a big club with a lot of potential. The perception of us from the 1990s is remarkable particularly.
Levy has structured the club to maximise performance and stablility regardless of who is "head coach" which shows in that in this 'disaster' of a season we've finished 6th. The individual quality throughout the squad is greater than at any time i can remember.
Every club makes dud appointments, but looking back, there were clear reasons why we went for who we did at the time and there are no guarantees in life, let alone football. All you can do as chairman is seek the maximum amount of advice, put measures in place to maximise the chance of success, but you will never be able to guarantee a successful coaching appointment.
