Ed Reed: F
Ed Reed was considered a huge offseason signing for the Texans, as it was believed he would drastically improve the team's coverage issues.
Reed, though, never really contributed to the defense. He missed the first two games of the season with a hip injury, but even when he did come back, he struggled to make more of an impact than when he was sitting on the bench.
Reed did nothing to help force turnovers or improve team coverage—which is why he was brought in—and he struggled mightily when it came to open-field tackling. He was soon cut after making disparaging remarks about the coaching staff, and his overall time with the Texans was largely a waste.
Danieal Manning: B+
Like so many other Texans players, Danieal Manning's season was cut short due to injury. However, even though he only played in six games, it was clear that he was much improved from the previous season.
His coverage was no longer a liability, and his ability to make plays against the run was just as present as it was before. He was an integral part of the defense, and it was a major loss when he went down for the season.
D.J. Swearinger: B
Drafted in the second round, D.J. Swearinger was not expected to start this year with both Ed Reed and Danieal Manning ahead of him on the depth chart.
However, due to Reed's release and Manning's injury, Swearinger found himself with a wealth of playing time, and he did not overly disappoint.
He proved himself to be the ferocious tackler that everyone knew he was when he was drafted, but it was his coverage that was the surprise. While it was not tremendous, it was certainly average, and that is more than what was expected considering most analysts believed he needed at least a season to adapt to NFL secondary play.
Shiloh Keo: B-
While Shiloh Keo is not perceived to be a solid player at all, he actually put together quite a good season this year, and he is certainly worthy of keeping on the roster as a backup.
He proved himself adequate in coverage, and he was also decent against the run. He should also only continue to improve.
