Jagielka needs his hand held and always has done. In the physical aspects of defending, right across the spectrum he is generally excellent - pace, strength, tackles, headers, blocks, last-ditch challenges - but mentally and positionally he is hopeless. The Lescott/Jags partnership was a fortress because Lescott had an effortless confidence about him. Heitinga (for all his faults) & Stones (for all his youth) are the same: they provide leadership, organisation, intuitive positioning, communication, and actually, balls. They are willing to be brave in a different sense - not throwing themselves in front of shots, but taking an extra touch or passing it short instead of smashing it out, or being confident enough that they'll win the second ball instead of making every first one a 50-50.
Jagielka and Distin are two of the same, and they never complemented each other. Individually there was hardly a striker who could get past them but as a unit they were often at 6s and 7s. Their complimenting mentalities are the worst: all smiles, jokes, back-slapping and high-fiving as they trip over their own feet and give assists to opposition strikers or smash the ball out of play for no reason or panic and treat the ball like a hot potato when we're in possession. These elements, I agree, have been harmful for a while. We should have all known when Jagielka laughed in Lukaku's face at the concept we might be a challenging force in football that this is never a man who should have captained Everton.
