He said Terry drags his team mates down with him but that is purely not the case. If anything when he's backed into a corner he normally comes out fighting and it makes him more determined.
I'm merely explaining why the notion "Terry has to go because he is a leader" is completely false.
First, the whole concept of a "leader" is rather odd, these people are adult professionals, they don't need daddy to hold their hands. You do need organisers on the field but many people can do that.
Secondly, i don't know what you do for a living, but in any kind of workplace you'll eventually run into person in a leadership position who is a complete ****. Since you're expected to behave professionaly and need to earn monies for that next FM edition, you have to get along with them. But if the same person shows up at private BBQ and still acts in this manner, nobody cares what they have to say , no matter how much they talk and how much chest thumping they do. If this metaphore is somehow unclear, Chelsea is a workplace, BBQ is England team , and Terry is a ****.
Last but not least, what does it matter if Center Back is determined or not. Lets say you have two CBs who are not determined and give up easily. What are they going to do, lie down and stop defending? I can see how it matters for strikers or midfield or maybe even full backs. CB? Not really. Anyone who made it up this level is already determined enough.
I get what you are trying to say, but you're using some artificial concepts that don't even apply to real world half the time. Passion, determination, leadership? Terry is not a warrior from World of Warcraft, he's a guy running in tight shorts for a living.
