After reading through all of the post on this topic a couple things come to mind..
1st- We have one of the best DB coaches in the country (Saban).. Stop complaining about our DB's needing more coaching on their technique. They get coached as well as any in the country.. You have to apply what you learn for it to work. We will continue to recruit tall corners for the future and Saban will teach them tech...
2nd- Javey is developing into a good corner.. Not great corner.. Don't forget he only has one year of playing time under his belt.. He is still learning. His speed can only help him so much and much of the time he is at the "Star" and not on the corner.
3rd- KJ is as good as we have in a lock-down corner.. However, with the size of today's WR he is overmatched most of the time when facing a very good Offensive team. For the most part he plays the best tech. but does not have the size to overcome any mistakes.
Finally, I don't care if you have Charles Woodson, Antoine Winfield or the great Deon Sanders at CB. If you don't have a solid pass rush, a good QB will pick you apart. Look at 1992.. We had good corners but we had two guys on both sides of the line that could rush a passer that made them look like great corners most of the time. The Pass Rush is the key..Pressure the QB and your CB's will look like All Stars...
