Noticed Paul Kuharsky posted an article on his ESPN Blog - the Texas appear to have bowed out of the Nnamdi race, but still received a nice parting gift - Johnathan Joseph.
Joseph isn't Nnamdi, but he is a damned good corner whose talents were wasting away in Cincinnati. ESPN rated him the #2 free agent corner;
Joseph is a good combination of size, strength and athleticism for a perimeter defender. He is explosive, quick and sharp out of his breaks. Joseph gets off the ground well and has very good overall speed. He reads plays well in zone and can stay on his opponent's hip in man coverage. He is a solid run-support player and a reliable tackler in the open field. Joseph has had some durability concerns throughout his career, but when healthy, he's an excellent cornerback.
The Jags and the Texans are using their cap space to upgrade their defense. The Colts and Titans have done little (outside of the Titans signing Matt Hasselbeck) - the gap between the Colts appears to be closing for both teams.
The Texans still need to add a true defensive tackle and work on their ends - without a solid d-line those linebackers will take a lot of unneeded shots, and DeMeco Ryans is still coming off his the blown ACL. They also need to work on the secondary (though Daniel Manning, S, was a nice addition). I'm not sure if moving Glover Quinn to FS is the answer, but the addition of Joseph will let them mask some of their deficiencies.
