sherman- bigger++, more physical/better tackler++, jumps higher, smarter, more clutch
deion- faster++, more agile+, better hand-eye coordination
roughly equal- competitiveness, work ethic, bravado, receiver mentality (when balls in air), hands

deion was a playmaker with the ball in his hands. ran 4.1-4.2 to sherms 4.5-4.6. super-fast acceleration. could change direction at high speed, which made him an electric punt returner, and in my opinion was the best return man of all time. he could get fooled in coverage but had the speed to recover. if he intercepted, he had a great chance of taking it to the house... from anywhere on the field.
sherman, at 6'3" with long arms, a 39 inch vertical, and a receiver mentality is a nightmare on jump balls. smart teams wont challenge him down the sideline. studies his opponents, reads their formations, qbs and receivers, and then takes advantage. he doesnt have near the acceleration and agility that deion had, but he usually gives himself enough room to work with so the receiver never gets a step on him. sherman is a better tackler no doubt, and it matters. teams would run at deion. they wont purposely run at sherm, and if they do, they bring #s.
different eras, and much different styles. but at this rate, sherman is the better overall corner. ill say this though, neon deion was fun to watch- was still a great (top 5) shutdown corner and was a far better playmaker when he had the ball... being one of the best playmakers of all time.
