of course it’s relevant. Ferdinand and Terry were playing week in week out as integral parts of great teams, also playing constantly in the CL. It’s even why I threw in the David May example, that it’s not just about titles. They helped make these teams great.
he was never as good as Rio and Terry - look at it objectively, and it’s clear to see that. If King didn’t have any injury issues and had the career he did, even spurs fans wouldn’t argue it - but instead (and it’s only natural to do so as a fan), you fill in all the blanks and months / years of injuries and lack of training with world class performances.
I’ll give you another example, which has been debated on here, Louis Saha. For around 18 months he was brilliant, and he could have been one of the PL great strikers, if not for his injury issues and mentality. The reality is he wasn’t, because he didn’t actually do it, despite what his potential may have been.
when fans come out with phrases like “we will never know” - people naturally assume they would have been better. No one thinks, well if he’s have been fit his entire career, perhaps he would have been crap in all those games he missed?
I don’t imagine you will find many people who aren’t spurs fans arguing King was as good as Rio or Terry.
