Your sarcastic tone of a response implied they shouldn't have left because they simply "enjoyed just sitting on a bench".
Oh and how dare I counter your sarcasm "fact-fuelled" and well thought reponse with some actual facts about what each player got up to. This is an internet football discussion forum where people discuss football. Ground breaking, I know.
Feel free to point out where I said we got relegated in 2009. All of them went to play at a higher level with varying success including promotions and appearances in the Premier League on a higher wage. All of which they wouldn't have achieved had they "stayed at Coventry City like they should have" (what this thread is actually all about).
Ask 99.999999% of professional footballers what they would rather do and you will soon realise your "I would rather play every game and be loved by the fans, than play a handful and be "1 of those players" that gets forgotten after a short breath. Personal choice." is an absolute fallacy in modern day football. Even then, I'd argue playing in promotion winning sides is better than playing for us in the late 00's, its an argument I'm very confident of winning that one actually.
Its a short career to these guys so they try and make as much money as possible, which is human general nature.
The issue here is they all evidently had better careers than if they'd had stayed with us unless:
a) You think everyone that plays for us is a fan and loves the club as much as you and I
b) They don't see their job as a, you know, job
c) They were deluded
Like I said, Sky blue tinted specs.
