In the past two seasons, Kareem Jackson has been a centerpiece of attention for the Texans' secondary.
He was either forgetting to turn his head when the ball was in mid-air, struggling to stay close to his assignment or getting flagged for an unnecessary pass-interference penalty.
Yeah, those were the days.
Recently, however, Jackson has been flying under the radar. The reason for this is because he is actually playing quite well.
He has displayed drastically-improved coverage skills, and there are times when he actually can be mistaken for a very good cornerback.
Also, it appears that Jackson is surprisingly rotating his head when the ball is in mid-air, which highly contributes to the chances that he will not give up a huge pass play.
All in all, Jackson is playing with much more confidence than he has in the past two seasons.
This is very important, as he will have quite the test on Sunday.
Since there is no clear No. 1 receiver on Denver, it is quite likely that Jackson will see a lot of both Eric Decker and Demaryius Thomas. He will have to, therefore, be able to show that his dramatic improvement over the course of the offseason will be enough for him to be able to cover two solid receivers.
The Texans must find ways to slow down Peyton Manning in this game, and Kareem Jackson's ability to effectively cover one of their receivers will be extremely important.
