Remember when none of our corners located the damn football? We had a secondary drought. Right around when we drafted Chung and proceeded to let him walk to philly. He learned how to cover in philly. Then he came back and really fit in with the new cover talent in town.
Physical, man corners are more disruptive. Period. The skills translate to run support. Of the 16 cb/ db's listed on the team roster, only one comes in listed under 5' 10", 4 are 5' 11, and 7 come at 6'+. There's a similar drift to size (and I'd imagine length to match) on offense at WR. It seems like everyone new is well over 6'.
