For anyone one who is playing Corner for their local rec. team, school, etc. I have a couple tips you might want to know, and could use.
Stance: Every corner must have some sort of low-to the knee stance. This is essential when back-pedalling into your respective coverage.
Back-pedalling: Back-Pedalling is essential when defending any reciever on any coverage, using different B-P patterns to the corresponding route is very helpful, and can put you in a great position to make a play on the ball.
Man Coverage: Man coverage is basically you and the opposing reciever. Most corners like to use the term "island" to portray the reciever and you are the only ones on that island, and you must defend him with anything you have.
Man Coverage Strategy: When you play man-coverage it's a good idea to get into a low-stance and stare at the hips of the reciever. Wherever he goes, you go all corresponding to his hips. Often corners won't look at the recievers hips and will glance at the QB just for a reaction, and end up getting beat on a short slant or long streak route because basically they lost the reciever when they glanced at the QB. When you follow the recievers hip's, you can see the slant or the cut in whatever route opposed to a different strategy that might likely get you beat...
Zone Coverage: In zone coverage, it's almost the exact opposite of man. In a zone you are reletively far away from the LOS (line of scrimmage) and will have to depend on your safeties alot more than usual. But the Zone is effective especially against big reciever sets such as a trips bunch and generally should allow to make a play on the ball while looking at the QB...
Zone Coverage Strategy: When I play zone, I like to sit back and glance at the reciever just to get a feeling where he is, then turn my attention to the QB. Often you can spot a QB's target just by looking at his eyes (maybe it's just me). Anyway, when the play starts don't pay close attention to the reciever unless he enters your zone, instead focus on the QB and watch his feet and react if neccesary. When a reciever enters your zone, be active, and make sure you keep your hips moving wherever the reciever goes, you should more times than not, be able to make a play by shifting yourself towards wherever the reciever is, if the QB throws it the ball that way. Zone can be complicated to explain since there are so many types of zone, but you get the picture.
