I think a lot of folks in here missing something. A no. 1 corner and a shutdown, on an island corner, are 2 very very different things. There are very few 'island' corners in this league. There are 32 no. 1 corners in this league.
You don't find 'island' CBs drafting in the 20s every year. A lot of you peoples expectations are way over board. Good grief.
