I think Height although it can be important. Is a bit overblown when it comes to CB position. Barron Miles was 5'8" tall yet I would take him over anybody on the team right now. No matter their height. Now he may be an extreme example as I believe he is the greatest CB we ever had. The NFL was afraid of his height, so he went to Canada and became the greatest CB in the history of that league.
Again, Barron was a physical freak, I just hope our coaches do not get too wrapped up in the NFL measurables. I know I made that mistake with Ameer. Where would we have been his senior year without him. Just saying.
