I agree. Jack's progression has been impressive. Good luck to the combatants.
i like the way he's 'quiet' in his personality, very understated..i mean not comparing with others ..
each one has a personality we can like - others are more boisterous, others are very overtly intense, others are more stoic, others boyish or girlish, etc..each one they have a personality that's nice or goes well with their game.
but i like best when a player's particular personality is MATCHED by his or her game.
this is the way i also like jack sock. he moves about like a 'nobody'
but his game ''matches' in the OPPOSITE way...it's the game a ''somebody".
he most reminds me in this ''mismatch'' in ''understated nobody" persona with a hidden danger ...with the grand enormous game of one of my favorites of all time whose career i followed right from just before his first slam to the very, very end when everyone was writing him off -- PETE SAMPRAS.
probably not quite at the same very olympus-like heights as sampras -- but much like it, at least to me , because no fan can have followed that guy's career the way i did, lol.
i know, i BRITBOX would know just as much -- right Britbox?
you better back me up on this!! lol
