I think the price each player cost is pretty similar as you point out. If Jeka can be half the player Carey was we're in business.Anyway Carey looked like from memory he had a great leap I remember him taking marks over the pack on his chest once he hurt his shoulders.
Style wise Carey would take high chest marks running back with the flight regularly, even pre-shoulder (pre him ditching the number 40 for 18 even). North set up their fwd line,to let him run back with the flight like that. It was almost his trademark move.
Jekka gets it at the apex of his leap though, more like Nick Riewoldt did.
Carey would also mark above his head pre shoulder, but it was normally with bent elbows even from early on, almost like he had to fight the urge to take a chest mark (his leap allowed him take pretty much anything on his chest).
