I said I didn't see how Corn is automatically the
#1 corner on the team. Corn is a very good nickel corner but IMO Tracy Howard was / is a better field corner for comparison.
What makes him a very good "nickel corner", IYO?
If you have ever played and/or coached a defense, you would know that the field corner isn't necessarily the best corner or best in coverage. The best cover guy usually plays the boundary. In college (wider space between the hashes), the easier throw is to the short side of the field. If you want to throw a quick pass to the sideline, you usually throw to the boundary, which is why you want your best cover guy on the boundary. More passes are going to go towards the boundary, so play your best cover guy at the boundary. Throwing to the field side requires timing and a stronger arm. The CB also has more time to recover. If you're thinking that you can isolate a player more to the field side, then you're neglecting the fact that he's going to have inside help by both the safety and LB. Only in trips, with the 1 WR to the wide side against cover 3, is he really isolated. Even then it's a tough throw, because the corner really emphasizes staying inside by either splitting the wr in half with his stance or he's complete inside (leverage). Some coaches move around their best WRs and have certain corners follow them, which can be at nickel, field, or boundary.
Elder, IMO, was our best corner in coverage last year. There's plenty of examples, but the one play that impressed me the most is when I saw him keep up and bat down an over the shoulder pass to Kermit Whitfield (one of the fastest players in the NCAA) on a deep crossing pattern. Not to many DBs can do that. That's a long developing play, that with good ball placement, the safety's (who wasn't there) only going to be able deflect the ball.
